Protein-ribulosamine 3-kinase, chloroplastic

342 amino acids

Phosphorylates low-molecular-mass and protein-bound erythrulosamines and ribulosamines, but not fructosamines or psicosamines, on the third carbon of the sugar moiety. Protein-bound erythrulosamine 3-phosphates and ribulosamine 3-phosphates are unstable and decompose under physiological conditions. Thus phosphorylation leads to deglycation (By similarity).

Belongs to the fructosamine kinase family.
