Adenosylhomocysteinase (AHCY), human, recombinant

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 2-432aa. Protein Length: Full Length of Mature Protein. Tag Info: N-terminal 6xHis-SUMO-tagged. Target Protein Sequence: SDKLPYKVAD IGLAAWGRKA LDIAENEMPG LMRMRERYSA SKPLKGARIA GCLHMTVETA VLIETLVTLG AEVQWSSCNI FSTQDHAAAA IAKAGIPVYA WKGETDEEYL WCIEQTLYFK DGPLNMILDD GGDLTNLIHT KYPQLLPGIR GISEETTTGV HNLYKMMANG ILKVPAINVN DSVTKSKFDN LYGCRESLID GIKRATDVMI AGKVAVVAGY GDVGKGCAQA LRGFGARVII TEIDPINALQ AAMEGYEVTT MDEACQEGNI FVTTTGCIDI ILGRHFEQMK DDAIVCNIGH FDVEIDVKWL NENAVEKVNI KPQVDRYRLK NGRRIILLAE GRLVNLGCAM GHPSFVMSNS FTNQVMAQIE LWTHPDKYPV GVHFLPKKLD EAVAEAHLGK LNVKLTKLTE KQAQYLGMSC DGPFKPDHYR Y. Purity: Greater than 90% as determined by SDS-PAGE. Endotoxin: Not test. Biological Activity: n/a. Form: Liquid or Lyophilized powder. Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0. Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20 °C/-80 °C. Our default final concentration of glycerol is 50%. Customers could use it as reference. Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20 °C/-80 °C. The shelf life of lyophilized form is 12 months at -20 °C/-80 °C. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4 °C for up to one week. Relevance: 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. Reference: Sequence of full length cDNA for human S-adenosylhomocysteine hydrolase.Coulter-Karis D.E., Hershfield M.S.Ann. Hum. Genet.53:169-175(1989). Function: 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.
