Rossmann fold — An example of the Rossmann fold, a structural domain of a decarboxylase protein from the bacterium Staphylococcus epidermidis (PDB ID 1G5Q) with the bound flavin mononucleotide cofactor shown. The Rossmann fold is a protein structural motif found … Wikipedia
Beta sheet — The β sheet (also β pleated sheet) is the second form of regular secondary structure in proteins consisting of beta strands connected laterally by three or more hydrogen bonds, forming a generally twisted, pleated sheet (the most common form of… … Wikipedia
