Novel Cofactors: Volume 58

A cofactor is a component part of many enzymes and functions by uniting with another molecule in order to become active. The use of cofactors to supplement the native amino acids of a protein is essential to maintain the chemical capabilities necessary for organisms to survive. This volume focuses on the significant advances of the past decade in identifying and describing new cofactors--either small molecules or those derived posttranslationally.
