IUBMB Enzyme Nomenclature

EC 6.3.2.21

Accepted name: ubiquitin—calmodulin ligase

Reaction: n ATP + calmodulin + n ubiquitin = n AMP + n diphosphate + (ubiquitin)n-calmodulin

Other name(s): ubiquityl-calmodulin synthase; ubiquitin-calmodulin synthetase; ubiquityl-calmodulin synthetase; uCaM-synthetase

Systematic name: calmodulin:ubiquitin ligase (AMP-forming)

Comments: Specific for Ca2+-calmodulin from vertebrates. At least three ubiquitin molecules can be coupled to lysine residues in calmodulin.
