Domain

Pectinesterase inhibitor domain (IPR006501)

Short name: Pectinesterase_inhib_dom

Domain relationships

None.

Description

This entry describes a plant domain of about 200 amino acids, characterised by four conserved Cys residues, shown in a pectinesterase inhibitor from Kiwi to form two disulfide bonds: first to second and third to fourth. Roughly half the members of this family have the region described by this entry followed immediately by a pectinesterase domain, IPR000070. This suggests that the pairing of the enzymatic domain and its inhibitor reflects a conserved regulatory mechanism for this enzyme family [PMID: 10880981].
