Q944I4 · GLYK_ARATH

Function

function

Catalyzes the concluding reaction of the photorespiratory C2 cycle, an indispensable ancillary metabolic pathway to the photosynthetic C3 cycle that enables land plants to grow in an oxygen-containing atmosphere.

Isoform 3

Cytoplasmic D-glycerate 3-kinase that constitutes a photorespiratory bypass that alleviates fluctuating light-induced photoinhibition (PubMed:29129375).

Catalytic activity

Pathway

Photosynthesis; photorespiration; 3-phospho-D-glycerate from glycine: step 4/4.

Features
