Phosphoglucan water dikinase, CB20 domain (IPR034848)

Short name: CBM20_water_dikinase

Overlapping homologous superfamilies

Domain relationships


This domain is found in the chloroplast-encoded phosphoglucan water dikinase (PWD), one of two enzymes involved in the phosphorylation of plant starches leading to starch turnover. PWD/GWD3 primarily catalyses phosphorylation at the C-3 position of the glucose unit of preferably pre-phosphorylated amylopectin [PMID: 15686522, PMID: 15618411]. In addition to the CBM20 domain, phosphoglucan water dikinase contains a C-terminal pyruvate binding domain [PMID: 17666166].
