Identification and nucleotide sequence of a developmentally regulated gene encoding a eukaryotic histone H1-like protein from Chlamydia trachomatis.

Molecular cloning and expression of hctB encoding a strain-variant chlamydial histone-like protein with DNA-binding activity.

Two DNA-binding proteins with similarity to eukaryotic histone H1 have been described in Chlamydia trachomatis. In addition to the 18-kDa histone H1 homolog Hc1, elementary bodies of C. trachomatis possess an antigenically related histone H1 homolog, which we have termed Hc2, that varies in apparent molecular mass among strains. We report the molecular cloning, expression, and nucleotide sequen...

Regulation of the Chlamydia trachomatis histone H1-like protein Hc2 is IspE dependent and IhtA independent.

The chlamydial histone-like proteins, Hc1 and Hc2, function as global regulators of chromatin structure and gene expression. Hc1 and Hc2 expression and activity are developmentally regulated. A small metabolite that disrupts Hc1 interaction with DNA also disrupts Hc2 interactions; however, the small regulatory RNA that inhibits Hc1 translation is specific to Hc1.

Sequence specific binding of chlamydial histone H1-like protein.

Chlamydia trachomatis is one of the few prokaryotic organisms known to contain proteins that bear homology to eukaryotic histone H1. Changes in macromolecular conformation of DNA mediated by the histone H1-like protein (Hc1) appear to regulate stage specific differentiation. We have developed a cross-linking immunoprecipitation protocol to examine in vivo protein-DNA interaction by immune preci...

Bioinformatic and empirical analysis of a gene encoding serine/threonine protein kinase regulated in response to chemical and biological fertilizers in two maize (Zea mays L.) cultivars

Molecular structure of a gene, ZmSTPK1, encoding a serine/threonine protein kinase in maize was analyzed by bioinformatic tool and its expression pattern was studied under chemical biological fertilizers. Bioinformatic analysis cleared that ZmSTPK1 is located on chromosome 10, from position 141015332 to 141017582. The full genomic sequence of the gene is 2251 bp in length and includes 2 exons. ...
