Purity > 90% as determined by SDS-PAGE. MW: 53kDa. Full Length: 1-448aa. N-terminal 6xHis-tagged. Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast). Adenosylhomocysteine is a competitive inhibitor of S-adenosyl-L-methionine-dependent methyl transferase reactions; therefore adenosylhomocysteinase may play a key role in the control of methylations via regulation of the intracellular concentration of adenosylhomocysteine.
