Abstract
Disclosed are genes, termed “yacM” and “yqeJ,” which are essential for survival for a wide range of bacteria, such as Streptococcus pneumoniae, Bacillus subtilis, and E. coli. These genes and the essential polypeptides they encode can be used to identify antibacterial agents for treating a broad spectrum of bacterial infections.
Claims8
A method for determining whether a test compound is a candidate antibacterial compound, the method comprising:
- (a) contacting an S-yacM (SEQ ID NO.:2) or an S-yqeJ (SEQ ID NO.:5) polypeptide with the test compound;
- and
- (b) detecting interaction of the test compound with the S-yacM or S-yqeJ polypeptide, wherein an interaction indicates that the test compound is a candidate antibacterial compound.
A method for determining whether a test compound is an antibacterial agent, the method comprising:
- (a) contacting an S-yacM (SEQ ID NO.:2) or an S-yqeJ (SEQ ID NO.:5) polypeptide with a test compound;
- (b) detecting a decrease in biochemical activity of the polypeptide contacted with the test compound, wherein a decrease in biochemical activity indicates that the compound is a candidate antibacterial compound;
- and
- (c) determining whether the candidate antibacterial compound inhibits growth of bacteria, relative to growth of bacteria cultured in the absence of the candidate antibacterial compound, wherein inhibition of growth indicates that the candidate antibacterial compound is an antibacterial agent.
