Recognition site
SourceAn E.coli strain, that carries the cloned M.HspAI gene from Haemophilus species AI.
DescriptionM.HspAI Methyltransferase modifies the internal cytosine residue (C5) in the recognition sequence forming 5`-G(5mC)GC-3`/3`-CG(5mC)G-5`.
Unit definitionOne unit of the enzyme is the amount required to protect 1 μg of Lambda DNA in 1 hour at 37°C in a total reaction volume of 20μl against cleavage by HspAI restriction endonuclease.
Reaction bufferSE-buffer B + SAM
Optimal temperature
Storage conditions10 mM Tis-HCl (pH 7.4); 0.1 mM EDTA; 10 mM 2-mercaptoethanol; 100 mM NaCl; 50% glycerol. Store at -20°C.
NotesTo obtain 100% activity, SAM should be added to the 1x reaction mix to a final concentration of 0,08 mM.
