Chains	Enzyme Name	Description	Catalytic Residues
A	[ribulose-bisphosphate carboxylase]-lysine N-methyltransferase M-CSA #604	Ribulose-1,5-bisphosphate carboxylase-oxygenase large subunit N-methyltransferase enzymes (LSMTs) uses S-adenosyl methionine to methylate Lys 14 of the Rubisco large subunit. Lys 14 is situated in the flexible N-terminal tail of the large subunit, and the precise role of its methylation is not clear. It does not affect the activity of Rubisco but may be involved in targeting other proteins to interact with the tail.
