Arginine-dependent gene regulation in Streptococcus gordonii ahrC regulator knockout

ABSTRACT: We have previously shown that responses of the oral bacterium Streptococcus gordonii to arginine are co-ordinated by three paralogous regulators: ArcR, ArgR and AhrC. This set of experiments was designed to assess the effects of the AhrC gene regulator on global gene expression in Streptococcus gordonii under high arginine or following a shift to no arginine.

Responses of Streptococcus gordonii to arginine restriction

Project description:Our previous work has indicated that extracellular arginine concentrations may be an important stimulus for gene regulation in S gordonii. Here cells were cultured in a chemically defined medium (CDM) to mid exponential phase . Cultures were split and resuspended in either CDM or CDM lacking arginine. After 30 mins RNA was extracted and gene expression was monitored using an Agilent microarray.
