A beta-lactamase from Mycobacterium fortuitum D316 was purified and some physico-chemical properties and substrate profile determined. On the basis of its N-terminal sequence and of its sensitivity to beta-iodopenicillanate inactivation, the enzyme appeared to be a class A beta-lactamase, but its substrate profile was quite unexpected, since nine cephalosporins were among the eleven best substrates. The enzyme...
