Bca77I: a new type-II restriction endonuclease from Bacillus caldolyticus cutting at the (A/T) increases CCGG(A/T) site.
We describe a new restriction enzyme recognizing a degenerate hexanucleotide sequence and cleaving the 5'-W increases CCGGW site (W = A or T). This enzyme cuts with high efficiency all four permutations of this sequence; ACCGGA (TCCGGT on the opposite strand), ACCGGT and TCCGGA. Methylation of the external cytosine completely blocks restriction while methylation of the internal cytosine only decreases the rate of restriction activity.
