Glucose-1-phosphate adenylyltransferase (IPR011831)

Short name: ADP-Glc_PPase

Overlapping homologous superfamilies

Family relationships


This enzyme, glucose-1-phosphate adenylyltransferase, is also called ADP-glucose pyrophosphorylase. The plant form is an alpha2, beta2 heterodimer, allosterically regulated in plants [PMID: 15692569]. Both subunits are homologous and included in this entry. In bacteria, both homomeric forms of GlgC and more active heterodimers of GlgC and GlgD have been described [PMID: 24112771]. This entry describes the GlgC subunit only. This enzyme appears in variants of glycogen synthesis pathways that use ADP-glucose, rather than UDP-glucose as in animals.
