En. Zheleznyakova et al., A site-specific endonuclease from thermophilic strain Bacillus species ZE is a ClaI isoschizomer, BIOCHEM-MOS, 63(12), 1998, pp. 1424-1429
Strain Bacillus species ZE with a maximal yield of the Clot isoschizomer wa
s chosen from 12 natural thermophilic strains producing Clot isomers. The y
ield is 110 times higher than that of the ClaI prototype endonuclease from
Caryophanon latum L. The enzyme is sensitive to DNA dam-methylation and is
highly stable under storage.
