ID 2.1.1.127 DE [ribulose-bisphosphate carboxylase]-lysine N-methyltransferase. AN ribulose-bisphosphate-carboxylase/oxygenase N-methyltransferase. AN RuBisCO LSMT. AN RuBisCO methyltransferase. CA L-lysyl-[ribulose-1,5-bisphosphate carboxylase] + 3 S-adenosyl-L- CA methionine = 3 H(+) + N(6),N(6),N(6)-trimethyl-L-lysyl-[ribulose-1,5- CA bisphosphate carboxylase] + 3 S-adenosyl-L-homocysteine. CC -!- The enzyme catalyzes three successive methylations of Lys-14 in the CC large subunits of hexadecameric higher plant ribulose-bisphosphate- CC carboxylase (EC 4.1.1.39). CC -!- Only the three methylated form is observed. CC -!- The enzyme from pea (Pisum sativum) also three-methylates a specific CC lysine in the chloroplastic isoforms of fructose-bisphosphate CC aldolase (EC 4.1.2.13).
