The RFC clamp loader: structure and function. The eukaryotic RFC clamp loader couples the energy of ATP hydrolysis to open and close the circular PCNA sliding clamp onto primed sites for use by DNA polymerases and repair factors. [] Structural studies reveal clamp loaders to be heteropentamers.
Get a quoteMar 25, 2020 · A bootloader, also known as a boot program or bootstrap loader, is a special operating system software that loads into the working memory of a computer after start-up. For this purpose, immediately after a device starts, a bootloader is generally launched by a bootable medium like a hard drive, a CD/DVD or a USB stick.The boot medium receives information from the computer's firmware …

Get a quoteinitial clamp loader binding followed by clamp opening (32, 33). However, the structure of this preopening intermediate state remains unknown. Moreover, it remains unknown how disease mutations perturb clamp loader function, as there is currently no structure of the human RFC complex. Here we describe a cryogenic electron microscopy (cryo-EM)
Get a quoteWhen an (optional) API layer is loaded, the loader links together a call chain that includes each function selected by the layer. At xrCreateInstance time the loader initializes all enabled API layers and creates call chains for each OpenXR command, with each entry of the resulting dispatch table pointing to the first element of that chain.

Instance Call Chain Example. For example, the diagram below represents what happens in the call chain for vkCreateInstance.
Get a quoteThe function of RFC has been aided by biochemical studies and structure determination, and also by the large body of research on the clamp loader of E. coli, which is also a heteropentamer like RFC and functions in a similar way. The studies to date answer many important questions, including the subunit organization that specifies how DNA is recognized, where clamps are bound to the clamp loader, and …
