DNA Clamp


It’s been a long time since I’ve posted a protein. But finally I’m back to the proteins and back for you, starting to fulfill your protein requests! The following drawing is inspired by a comment by pensatorkjh back in 2012.

Protein Data Bank ID: 3BEP
Protein Name: DNA Clamp
Organism: Escherichia coli
Title of the Drawing: “Even-Toed Ungulates

The DNA clamp is one of the most important cellular tools for DNA replication. It encircles the DNA helix which is situated in the center of the drawing and represents an emblem of even-toed ungulates. The clamp itself is drawn as a circle dance performed by deer, sheep, gazelles, and boars. The clamp slides along the DNA and ensures that the polymerase, the actual DNA copying machine, remains attached to the DNA strands. The clamp has distant analogy to a horse collar necessary for the carriage to remain on track.
