Lytic polysaccharide monooxygenases (LPMOs) are a recently discovered class of enzymes that employ a copper-mediated, oxidative mechanism to cleave glycosidic bonds. The LPMO catalytic mechanism likely requires that molecular oxygen first binds to Cu(I), but the oxidation state in many reported LPMO structures is ambiguous, and the changes in the LPMO active site required to accommodate both oxidation states of copper have not been fully elucidated. Here, a diffraction data collection strategy minimizing the deposited x-ray dose was used to solve the crystal structure of a chitin-specific LPMO from Enterococcus faecalis (EfaCBM33A) in the Cu(II)-bound form. Subsequently, the crystalline protein was photoreduced in the x-ray beam, which revealed structural changes associated with the conversion from the initial Cu(II)-oxidized form with two coordinated water molecules, which adopts a trigonal bipyramidal geometry, to a reduced Cu(I) form in a T-shaped geometry with no coordinated water molecules. A comprehensive survey of Cu(II) and Cu(I) structures in the Cambridge Structural Database unambiguously shows that the geometries observed in the least and most reduced structures reflect binding of Cu(II) and Cu(I), respectively. Quantum mechanical calculations of the oxidized and reduced active sites reveal little change in the electronic structure of the active site measured by the active site partial charges. Together with a previous theoretical investigation of a fungal LPMO, this suggests significant functional plasticity in LPMO active sites. Overall, this study provides molecular snapshots along the reduction process to activate the LPMO catalytic machinery and provides a general method for solving LPMO structures in both copper oxidation states.
Firstly, the interactive mode you may know from reviewing and updating failed snapshots can now also be used to step through failed tests one at a time. Credit goes to first-time contributor @NullDivision for implementing this feature!
Speaking of snapshots, one of the more exciting features we've shipped in recent years are Inline Snapshots, which landed in a minor release of Jest 23 almost three years ago. However, they came with the restriction that projects wanting to utilize them must be using Prettier to format their code, because that's what Jest would use to make sure the file it writes the snapshots into remains properly formatted.And so for most of these years, we've had a pull request in the pipeline to eliminate this restriction and allow using Inline Snapshots without Prettier. It has amassed well above a hundred comments, not even taking into account PRs split out from it and landed first, and even changed owner once after the initial submission by another first-time contributor, @mmkal under the hilarious working title 'Uglier Inline Snapshots'. With the stellar rise of Prettier in recent times, this improvement is now maybe less needed than back in 2018, but still, we know that feeling of getting into a project that does not use Prettier, and suddenly not being able to use inline snapshots anymore. Nevermore!
EBS snapshots are used to back up the data on your EBS volumes to Amazon S3 at a specific point in time. You can use the snapshots to restore previous states of EBS volumes. It is rarely acceptable to share a snapshot with the public. Typically the decision to share a snapshot publicly was made in error or without a complete understanding of the implications. This check helps ensure that all such sharing was fully planned and intentional.
For an added layer of security of your sensitive data in EBS volumes, you should enable EBS encryption at rest. Amazon EBS encryption offers a straightforward encryption solution for your EBS resources that doesn't require you to build, maintain, and secure your own key management infrastructure. It uses KMS keys when creating encrypted volumes and snapshots.
This control checks whether Amazon RDS snapshots are public. The control fails if RDS snapshots are public. This control evaluates RDS instances, Aurora DB instances, Neptune DB instances, and Amazon DocumentDB clusters.
For an added layer of security for your sensitive data in RDS DB instances, you should configure your RDS DB instances to be encrypted at rest. To encrypt your RDS DB instances and snapshots at rest, enable the encryption option for your RDS DB instances. Data that is encrypted at rest includes the underlying storage for DB instances, its automated backups, read replicas, and snapshots.
This control is intended for RDS DB instances. However, it can also generate findings for snapshots of Aurora DB instances, Neptune DB instances, and Amazon DocumentDB clusters. If these findings are not useful, then you can suppress them.
Backups help you more quickly recover from a security incident and strengthens the resilience of your systems. Amazon RDS provides an easy way to configure daily full instance volume snapshots. For more details on Amazon RDS automated backups, see Working with Backups in the Amazon RDS User Guide.
Identification and inventory of your IT assets is a crucial aspect of governance and security. You need to have visibility of all your RDS DB clusters so that you can assess their security posture and take action on potential areas of weakness. Snapshots should be tagged in the same way as their parent RDS database clusters. Enabling this setting ensures that snapshots inherit the tags of their parent database clusters.

Backups help you to recover more quickly from a security incident. They strengthen the resilience of your systems. Amazon Redshift takes periodic snapshots by default. This control checks whether automatic snapshots are enabled and retained for at least seven days.

VMware snapshots are much different. When you have a virtual disk there is an associated .vmdk file. When you take a snapshot, a new .vmdk will be created to write any of the changes. This DISKNAME-00001.vmdk will then store all of the deltas. VMware is using Copy on Write to then take any changes to the original DISKNAME.vmdk and write them to the DISKNAME-00001.vmdk.
VMware snapshots should be used carefully because they can quickly fill up the datastore they belong too. For instance a 40 Gb disk could potentially have a 40Gb snapshot file. There could also be another 40 Gb snapshot of that file so with 2 snapshots we could have tripled the amount of space used.
VMware uses the Copy-On-Write method for their snapshots. I see your point but have found this over and over again in the VMware documentation. =en_US&cmd=displayKC&externalId=1015180 and -51/index.jsptopic=%2Fcom.vmware.vsphere.vm_admin.doc%2FGUID-38F4D574-ADE7-4B80-AEAB-7EC502A379F4.html
The download links for dev snapshots are not featured on the Download page to avoid confusion for new users. Instead, browse our download repository and fetch the editor binary that matches your platform:
This page has the development versions from Beta 1.8 to present. Snapshots are written in the format YYwWWx, with YY being the 2-digit year, w standing for week, WW being the week of the year, and x being the number of snapshots in that week, like a being the first snapshot, b being the second snapshot, etc., or also is marked as -prex.
When recording and managing video content, there are many scenarios in which an individual will want to take snapshots of a video they have previously recorded. For example, a major retail corporation might need to take snapshots of a training video for the purpose of creating images for use in additional training materials. Alternatively, many content creators on Youtube will take a snapshot of their video footage in order to create a thumbnail that viewers can see when browsing the website for videos. With all this being said, CaseGuard Studio contains a snapshot feature that allows users of the software to take snapshots of their videos at the click of a button. 1e1e36bf2d
