Materials and Methods Materials. 55FeCl3 in 0.5 Mhc1 was purchased from ICN Corp. DEAE-cellulose was purchased from Whatman Corp. in the form of DE-52. Enterobactin was isolated from E. coli strain AN102 as previously described (Wayne et al., 1976).[55Fe] Ferric enterobactin, prepared according to the procedure for formation of ferric catecholates, and colicin B were obtained by the methods given by Hollifield & Neilands (1978). Bis (2, 3-dihydroxybenzoyl) lysine was synthesized in this lab-oratory by T. Peterson and A. Chimiak via a modification of the method of Corbin & Bulen (1969). Bio-Gels A5M and A. 5M were obtained from Bio-Rad Laboratories. Bacterial Strains. Bacterial strains derived from E. coli K12 include BN3040 and UT4400 andhave been previously described (Fiss et al., 1979). Plasmid DNA pGGCllO is a pBR322 derivative of pMC44 (Gayda & Markovitz, 1978), while E. coli B, E. coli B/r and Salmonella typhimurium LT2 are from laboratory stocks.
