4.4.1.11	L-methionine + H2O = methanethiol + NH3 + 2-oxobutanoate	mechanism	
4.4.1.11	L-methionine + H2O = methanethiol + NH3 + 2-oxobutanoate	cleavage of C-N bond in addition to C-S, C-Se and C-O bond at beta-position of amino acids by elimination and replacement reactions	
4.4.1.11	L-methionine + H2O = methanethiol + NH3 + 2-oxobutanoate	rate determining stage of the enzymatic reaction is deamination of aminocrotonate, important contribution of the sulfur atom and methylene groups to the efficiency of binding of substrates and inhibitors
