S-Adenosylmethionine 181-204 hypothetical protein Escherichia coli 37-42 9139683-8 1997 The cell-free homogenate of the transformant of E. coli with an expression vector of ORF-2 catalyzed the incorporation of S-adenosyl-L-methionine into menaquinone-8, indicating that ORF-2 encodes 2-heptaprenyl-1,4-naphthoquinone methyltransferase, which participates in the terminal step of the menaquinone biosynthesis.
