In enzymology an ubiquitin-calmodulin ligase (EC 6.3.2.21) is an enzyme that catalyzes the chemical reactionn ATP + calmodulin + n ubiquitin n AMP + n diphosphate + (ubiquitin)n-calmodulinThe 3 substrates of this enzyme are ATP calmodulin and ubiquitin whereas its 3 products are AMP diphosphate and (ubiquitin)n-calmodulin.This enzyme belongs to the family of ligases specifically those forming carbon-nitrogen bonds as acid-D-amino-acid ligases (peptide synthases).
