In vivo assessment of CbiB function. Cbl-dependent growth of the chromosomal cbiB mutants of serovar Typhimurium was assessed in minimal medium supplemented with glycerol, Cby, and DMB, demand in Cbl-dependent methionine synthesis. Strains: JE9283 (cbiB1265, which encodes CbiBA248T); JE9268 (cbiB1261, encodes CbiBW126Z); JE9266 (cbiB1260, encodes CbiBD181N); JE9535 (ΔcbiB1345, which encodes CbiBW126Z Δ127-319); JE8185 (ΔcbiB1309, which encodes ΔCbiB).
