Mt. Poch et Ga. Somkuti, ISOLATION OF SAGI, A NEW HAEIII ISOSCHIZOMER FROM STREPTOCOCCUS-AGALACTIAE, Applied microbiology and biotechnology, 43(2), 1995, pp. 282-284
A new HaeIII isoschizomer from Streptococcus agalactiae was isolated b
y a single-step purification method. The highly active restriction end
onuclease, SagI, was free of nonspecific nuclease activity and was sui
table for use in molecular biology procedures, The rapid isolation pro
cedure may be applicable for the recovery of other restriction endonuc
leases from bacteria.
