Reaction: 3 S-adenosyl-L-methionine + [fructose-bisphosphate aldolase]-L-lysine = 3 S-adenosyl-L-homocysteine + [fructose-bisphosphate aldolase]-N6,N6,N6-trimethyl-L-lysine
Other name(s): rubisco methyltransferase; ribulose-bisphosphate-carboxylase/oxygenase N-methyltransferase; ribulose-1,5-bisphosphate carboxylase/oxygenase large subunit εN-methyltransferase; S-adenosyl-L-methionine:[3-phospho-D-glycerate-carboxy-lyase (dimerizing)]-lysine 6-N-methyltransferase
Systematic name: S-adenosyl-L-methionine:[fructose-bisphosphate aldolase]-lysine N6-methyltransferase
Comments: The enzyme methylates a conserved lysine in the C-terminal part of higher plant fructose-bisphosphate aldolase (EC 126.96.36.199). The enzyme from pea (Pisum sativum) also methylates Lys-14 in the large subunits of hexadecameric higher plant ribulose-bisphosphate-carboxylase (EC 188.8.131.52) , but that from Arabidopsis thaliana does not.
