ABSTRACT:
A gene which provides resistance to at least one methionine derivative and is capable of enhancing accumulation of S-adenosyl-L-methionine (SAM) in a cell, a hybrid plasmid having the same, a cell transformed with the above hybrid plasmid, and a process for producing SAM using the above cell. According to the present invention, SAM, which has various therapeutic effects, can be producing in a large amount at a low cost.
