Cytidine deaminase, homotetrameric (IPR006262)

Short name: Cyt_deam_tetra

Overlapping homologous superfamilies

Family relationships



This family represents the small homotetrameric form cytidine deaminase, which is a zinc metalloprotein. It is found in humans and most bacteria. A related homodimeric form, IPR006263, with a much larger subunit is found in Escherichia coli [PMID: 10493793] and in Arabidopsis thaliana (Mouse-ear cress). Both types may act on deoxycytidine as well as cytidine [PMID: 11851403].
