Abstract

The gene of encodes the alternative factor , which bears strong homology to many bacterial factors, including and s and . Recently, a promoter was identified upstream of the late-cycle-expressed gene , which encodes the -histone-like protein 2 ( Yu & Tan, 2003 ). In this study it is shown that the product of chlamydial is an homologue. It was found that recombinant chlamydial , in combination with core RNA polymerase, initiates transcription from the -dependent promoter of . It was also demonstrated that the recombinant chlamydial does not recognize major factor -consensus-like sequences . In -infected cells, two transcripts were detected with 5′ ends located 18 (transcript I) and 54 bp (transcript II) upstream of the translational initiation codon at 16 and 30 h post-infection. When the temperature of cultures infected with was shifted from 35 to 42 °C, the transcript I increased dramatically. The levels of chlamydial , relative to EF-Tu, were greater throughout the exponential growth phase of the reticulate body, but lower late in the developmental cycle. These data support the hypothesis that plays a role in the regulatory network that allows chlamydiae to survive changes in its environment, enabling it to complete its unique developmental cycle.
