NCBI Protein Information
galacturonic acid kinase
NCBI Summary
Encodes a GHMP kinase family protein that acts as a galacturonic acid-1-phosphate kinase that catalyzes the production of galacturonic acid-1-phosphate. This is a precursor of the important cell wall building block UDP-galacturonic acid. Based on gene trap line GT8007, the gene appears to be expressed in a petal and stamen-specific manner, between flower stages 8 to 11, however, later RT-qPCR analysis demonstrates that the transcript is present throughout the plant in all tissues tested.

UniProt Comments
Sugar-1-kinase with a strict substrate specificity for the alpha-anomeric configuration of D-galacturonic acid (D-GalA) and ATP. Involved in the biosynthesis of UDP-galacturonic acid (UDP-GalA) from the salvaged GalA that is released during growth-dependent cell wall restructuring.
