A 7.5 kb BclI-fragment of Streptococcus pneumoniae DNA has been cloned in Escherichia coli HB101 using pBR322 as a vector. The new plasmid (pGL30) of 12.0 kb expresses a protein that has been characterized by biochemical, immunological and genetic methods as the inactive form (E-form) of the pneumococcal N-acetyl-muramyl-L-alanyl amidase (EC 3.5.1.28). Our results demonstrate that the E-form is the primary product of the lyt gene of S. pneumoniae. The inactive E-form can be converted to the active C-form in vitro by incubation of the E-form enzyme with choline-containing pneumococcal cell walls at low temperature in a similar way to enzyme production in the homologous system. The production of this protein in E. coli HB101 was 500-fold higher than in the homologous host. E. coli CSR603 containing pGL30 and labeled with [35S]methionine synthesized a 35 kd protein. pGL30 can transform at high frequency an autolysin-defective mutant of S. pneumoniae to the lyt+ phenotype.
