(Ribulose-bisphosphate carboxylase)-lysine N-methyltransferase explained

[ribulose-bisphosphate carboxylase]-lysine N-methyltransferase
Ec Number:2.1.1.127
Cas Number:139171-98-5
Go Code:0030785

In enzymology, a [ribulose-bisphosphate carboxylase]-lysine N-methyltransferase is an enzyme that catalyzes the chemical reaction

S-adenosyl-L-methionine + [ribulose-1,5-bisphosphate carboxylase]-lysine

\rightleftharpoons

S-adenosyl-L-homocysteine + [ribulose-1,5-bisphosphate carboxylase]-N-methyl-L-lysine

Thus, the two substrates of this enzyme are S-adenosyl methionine and ribulose-1,5-bisphosphate carboxylase-lysine, whereas its two products are S-adenosylhomocysteine and ribulose-1,5-bisphosphate carboxylase-N6-methyl-L-lysine.

Transferase Family

This enzyme belongs to the family of transferases, specifically those transferring one-carbon group methyltransferases.

The systematic name of this enzyme class is S-adenosyl-L-methionine:[3-phospho-D-glycerate-carboxy-lyase (dimerizing)]-lysine N6-methyltransferase.

Other names in common use include rubisco methyltransferase, ribulose-bisphosphate-carboxylase/oxygenase N-methyltransferase, ribulose-1,5-bisphosphate carboxylase/oxygenase large subunit, epsilonN-methyltransferase, S-adenosyl-L-methionine:[3-phospho-D-glycerate-carboxy-lyase''', and '''(dimerizing)]-lysine 6-N-methyltransferase.
