  1. a Gene name as annotated for Y. pestis strain KIM and/or CO92 or gene names (in parentheses) given herein based on the name of their E. coli homologs. Multiple names for the same gene are separated by commas. Genes of multi-component pumps are separated by dashes. The star (*) marks genes from multi-component pump gene clusters whose transcripts were analyzed by qRT-PCR. b Gene designations in the University of Wisconsin, TIGR, and SANGER Y. pestis genome databases. The Wisconsin column shows designations for all the genes in each predicted multi-component pump. TIGR and SANGER columns show only genes targeted in qRT-PCR. c Pump families assigned based on homology to known (super)family members from other organisms. MFS, major facilitator superfamily; SMR, small multidrug resistance family; ABC, ATP-binding cassette superfamily; RND, resistance-nodulation-cell division superfamily; MATE, multidrug and toxic compound extrusion family; DMT, drug/metabolite transporter superfamily; CDF, cation diffusion facilitator family; ArAE, aromatic acid exporter family; IT, Ion transporter superfamily; HCC, HlyC/CorC family. d Fold change values (FC) are means of triplicates ± standard errors and are presented in decreasing order. For polycistronic transcripts, qRT-PCR was conducted with primers targeting the first pump component-encoding gene of the operon. These genes are marked with a star. nd, transcript not detected in any of the three Y. pestis strains examined (wild-type, Yp pGEM-4Z, and Yp pGEM-RobYp).
