ENTRY       EC 6.3.2.21
NAME        Ubiquitin--calmodulin ligase
            Ubiquityl-calmodulin synthase
CLASS       Ligases
            Forming carbon-nitrogen bonds
            Acid--amino-acid ligases (peptide synthases)
SYSNAME     Calmodulin:ubiquitin ligase (AMP-forming)
REACTION    n ATP + Calmodulin + n Ubiquitin = n AMP + n Pyrophosphate +
            (Ubiquitin)n-calmodulin
SUBSTRATE   ATP
            Calmodulin
            Ubiquitin
PRODUCT     AMP
            Pyrophosphate
            (Ubiquitin)n-calmodulin
COMMENT     Specific for Ca2+-calmodulin from vertebrates. At least 3
            ubiquitin molecules can be coupled to lysine residues in
            calmodulin.
