Abstract

SUMMARY: We have cloned DNA fragments from 168S into , which produced a lytic zone on an agar medium containing cell wall. Sequencing of the fragments showed the presence of an open reading frame (ORF) which encodes a polypeptide of 272 amino acids with a molecular mass of 29919 Da. The deduced amino acid sequence showed considerable homology with that of the cell wall hydrolase gene of sp. (Potvin, C., Leclerc, D., Tremblay, G., Asselin, A. & Bellemare, G. (1988). and 214, 241--248). Accordingly, the gene was designated , for cell . The N-terminal amino acid sequence of gene product prepared from a clone was AIKVVKNLVSKSKYGLKCPN, which is consistent with that of the deduced sequence starting from Ala at second position from the initiation codon of the gene. A presumed δ promoter and a rho-independent terminator were found upstream and downstream of the ORF, respectively. A chloramphenicol-resistance determinant integrated into the ORF was mapped by PBS1 transduction, which indicated the gene sequence
