QT:{{”
Pseudoenzymes are proteins that cannot catalyze chemical reactions despite being clearly related structurally to functioning enzymes. Many enzyme families contain inactive members. For example, a number of human kinases lack at least one of the key amino acids necessary for catalysis of phosphate transfer [1]. Often pseudoenzymes still have biological roles, albeit non-catalytic. Some assist true enzymes in obtaining functional folds, some server as platforms for other proteins to interact, and some are escorts for proteins [2][3]. “}}
