Identification of the ubiD gene on the Escherichia coli chromosome.
نویسندگان
چکیده
The open reading frame at 86.7 min on the Escherichia coli chromosome, "yigC," complemented a ubiD mutant strain, AN66, indicating that yigC is the ubiD gene. The gene product, a 497-amino-acid-residue protein, showed extensive homology to the UPF 00096 family of proteins in the Swiss-Prot database.

Evaluation of the antibiotic resistance and prevalence of uropathogenic Escherichia coli and detection of traT gene in isolated from patients referred to Abadan hospitals during 2017-2018
Objective: Escherichia coli is one of the most important causes agents of urinary tract infection in human. Thus, identification of Escherichia coli resistance patterns seems to be necessary. traT gene has been reported variable in Escherichia coli strains isolated from urinary tract infection. Therefore, the aim of this study was to investigate the prevalence of uropathogenic Escherichia coli ...

متن کاملIdentification of Biofilm Encoding Genes (agg) in the Escherichia coli Isolates by Multiplex-PCR Method
Introduction: Biofilm is a collection of microbial cells that are irreversibly suppressed and mildly washed away. The aggR gene is located on the main plasmid (pAA), which codes for many actuator factors. The pathogen strains of EAEC have an aggR gene, the gene has been identified in six classes of pathogenic E. coli. Materials & Methods: In the present study, 60 stool samples from children ...
متن کاملRegulation of the isofunctional genes ubiD and ubiX of the ubiquinone biosynthetic pathway of Escherichia coli.
The expressions of the isofunctional genes ubiD and ubiX of the ubiquinone biosynthetic pathway of Escherichia coli were compared under a variety of growth conditions and in several genetic backgrounds. LacZ operon fusions were constructed and were inserted in single copies into strain MC4100 and into its fnr, arcA or hemA carrying derivatives. During aerobic growth the expressions of both ubiD...
متن کاملIdentification and characterization of aarF, a locus required for production of ubiquinone in Providencia stuartii and Escherichia coli and for expression of 2'-N-acetyltransferase in P. stuartii.
Providencia stuartii contains a chromosomal 2'-N-acetyltransferase [AAC(2')-Ia] involved in the O acetylation of peptidoglycan. The AAC(2')-Ia enzyme is also capable of acetylating and inactivating certain aminoglycosides and confers high-level resistance to these antibiotics when overexpressed. We report the identification of a locus in P. stuartii, designated aarF, that is required for the ex...
