Task: Class Definition Understanding (ontology: Sciences/Biology)

Which of the following definitions best describes 'protein-fructosamine 3-kinase activity'?

A. Catalysis of the reaction: ADP + thymidine = AMP + thymidine 5'-phosphate.
B. Catalysis of the reaction: Removal of an acetyl group from a lysine residue in a protein.
C. Catalyzes the reaction: 2-oxoglutarate + [protein]-L-arginine + O2 = [protein]-(3R)-3-hydroxy-L-arginine + CO2 + succinate.
D. Catalysis of the reaction: ATP + a [protein]-N6-D-fructosyl-L-lysine = ADP + H+ + a [protein]-N6-(3-O-phospho-D-fructosyl)-L-lysine.

Answer: Catalysis of the reaction: ATP + a [protein]-N6-D-fructosyl-L-lysine = ADP + H+ + a [protein]-N6-(3-O-phospho-D-fructosyl)-L-lysine.
