Those that supported the original findings of the array consist of the following PmrA-activated genes ( including the predicted protein products ) : STM1253 , putative inner membrane protein ; STM1269 , putative chorismate mutase ; STM4118 , putative integral membrane protein ; STM3968 , uridine phosphorylase ; STM4568 , thymidine phosphorylase ; STM0459 , AsnC family transcriptiona independent assays .
In addition , the lack of consensus PmrA-binding sites in the promoters of STM4568 suggested that these genes may be indirectly activated by PmrA .
