EC 2.7.1.172 Details
EC number
2.7.1.172
Accepted name
protein-ribulosamine 3-kinase
Reaction
ATP + [protein]-N6-D-ribulosyl-L-lysine = ADP + [protein]-N6-(3-O-phospho-D-ribulosyl)-L-lysine
Other name(s)
Fn3KRP, FN3K-related protein, FN3K-RP, ketosamine 3-kinase 2, fructosamine-3-kinase-related protein, ribulosamine/erythrulosamine 3-kinase, ribulosamine 3-kinase
Systematic name
ATP:[protein]-N6-D-ribulosyl-L-lysine 3-phosphotransferase
Comment
This enzyme plays a role in freeing proteins from ribulosamines or psicosamines, which might arise from the reaction of amines with glucose and/or glycolytic intermediates. This role is shared by EC 2.7.1.171 (protein-fructosamine 3-kinase), which has, in addition, the unique capacity to phosphorylate fructosamines [1]. The plant enzyme also phosphorylates [protein]-N6-D-erythrulosyl-L-lysine [2]. No activity with [protein]-N6-D-fructosyl-L-lysine [1,2].
