catalytic activity:Protein glutamine + alkylamine = protein N(5)-alkylglutamine + NH(3).,cofactor:Binds 1 calcium ion per subunit.,function:Catalyzes the cross-linking of proteins and the conjugation of polyamines to proteins. It is responsible for the later stages of cell envelope formation in the epidermis and the hair follicle.,PTM:Activated by proteolytic processing.,similarity:Belongs to the transglutaminase superfamily. Transglutaminase family.,subunit:This enzyme consists of two polypeptide chains, which are synthesized as a precursor form of a single polypeptide.,
