DNA methyltransferases affecting the sequence 5'CCGG.

RESUMO
B. subtilis phage SPbeta and Moraxella sp. code for DNA methyltransferases which methylate both cytosines of the sequence 5'CCGG. Experiments using a B. subtilis strain whose DNA is sensitive to HpaII and resistant to MspI degradation, indicated that methylation of the outer C of this sequence provides protection against the restriction enzyme MspI.
