The polyphosphate (polyP) operon was cloned from a genomic library of Serratia marcescens KCTC 2172 by Southern hybridization using E. coli ppk gene as a probe. The polyP operon was composed of a polyphosphate promoter, polyphosphate kinase (ppk) and exopolyphosphatase (ppx). A potential CRP binding

✦ Synopsis
SLP is a lambda-like bacteriophage specific for Serratia marcescens strains. Morphological studies have demonstrated that SLP virions present two cross-bar structures on its tail not described in bacteriophages specific for Enterobacteriaceae. SDS-polyacrylamide gel electrophoresis of major capsid proteins as well as electron micrographs are reported.
