Protein

Ribulose-1,5 bisphosphate carboxylase/oxygenase large subunit N-methyltransferase, chloroplastic

Gene

RBCMT

Organism
Pisum sativum (Garden pea)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Methylates 'Lys-14' of the large subunit of RuBisCO. Can also use with lower efficiency chloroplastic fructose-bisphosphate aldolases and gamma-tocopherol methyltransferase as substrates, but not a cytosolic aldolase.1 Publication

Catalytic activityi

3 S-adenosyl-L-methionine + [ribulose-bisphosphate carboxylase]-L-lysine = 3 S-adenosyl-L-homocysteine + [ribulose-bisphosphate carboxylase]-N6,N6,N(6)-trimethyl-L-lysine.
3 S-adenosyl-L-methionine + [fructose-bisphosphate aldolase]-L-lysine = 3 S-adenosyl-L-homocysteine + [fructose-bisphosphate aldolase]-N6,N6,N(6)-trimethyl-L-lysine.

Kineticsi

Kcat is 0.047 sec(-1) for S-adenosyl-L-methionine. Kcat is 0.038 sec(-1) for rubisco.
