Protein
Protein-ribulosamine 3-kinase, chloroplastic
Organism
Arabidopsis thaliana
Function
Initiates a process leading to the deglycation of proteins. 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.
Similarity
Belongs to the fructosamine kinase family.
