Thus , STM4118 may be a PmrA-activated gene responsible for modification of LPS core with pEtN in S. enterica serovar Typhimu-rium .
Strong matches to this sequence were detected in the promoter regions of STM4118 , STM1253 and STM1269 , but not in the other PmrA-activated genes .
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 .
