text_B: The fluorinase enzyme -LRB- , also known as adenosyl-fluoride synthase -RRB- catalyzes the reaction between fluoride ion and the co-factor S-adenosyl-L-methionine to generate L-methionine and 5 ' - fluoro-5 ' - deoxyadenosine , the first committed product of the fluorometabolite biosynthesis pathway .. catalyzes.
