ABSTRACT The transcription start sites for the tatABCD andtatE loci, encoding components of the Tat (twin-arginine translocase) protein export pathway, have been identified. Expression studies indicate that the tatABCD and tatEtranscription units are expressed constitutively. Translational fusion experiments suggest that TatA is synthesized at a much higher level than the other Tat proteins.

A chemically defined medium (FMC; B. Terleckyj, N. P. Willett, and G. D. Shockman, Infect. Immun. 11 :649-655, 1975) was used to compare the growth and amino acid requirements of 16 strains of group B streptococci, consisting of both laboratory-passaged organisms and fresh clinical isolates from adult and neonatal infections. The 5 standard Lancefield immunizing strains of group B streptococci, 090 (Ia), H36B (Ib), A909 (Ic), 18RS21 (II), and D136C (III), had doubling times in FMC (28 to 36 min) similar to those observed in Todd-Hewitt glucose broth (24 to 30 min). Similar doubling times were obtained with 11 clinical isolates growing in Todd-Hewitt glucose broth and FMC. The optimum buffering capacity of FMC was provided by 0.06 M sodium phosphate, and 1% glucose gave maximum cell yield. The group B streptococci, with minor exceptions, were very homogeneous in their amino acid requirements under both aerobic and anaerobic growth conditions. Phenylalanine, tyrosine, tryptophan, glutamate, arginine, valine, leucine, lysine, methionine, isoleucine, cystine, and histidine were required by all 16 strains under both aerobic and anaerobic growth conditions. In addition, threonine was required by all strains under aerobic growth conditions, whereas only 9 strains required threonine under anaerobic conditions. Serine was required by only 3 type III fresh clinical isolates aerobically, but not anaerobically. A requirement for glycine varied from strain to strain, apparently influenced by the oxidation-reduction potential of the growth medium.

Respiratory Electron Transport

Shewanella species are isolated from the oxic/anoxic regions of seawater and aquatic sediments where redox conditions fluctuate in time and space. Colonization of these environments is by virtue of flexible respiratory chains, many of which are notable for the ability to reduce extracellular substrates including the Fe(III) and Mn(IV) contained in oxide and phyllosilicate minerals. Shewanella oneidensis MR-1 serves as a model organism to consider the biochemical basis of this flexibility. In the present paper, we summarize the various systems that serve to branch the respiratory chain of S. oneidensis MR-1 in order that electrons from quinol oxidation can be delivered the various terminal electron acceptors able to support aerobic and anaerobic growth. This serves to highlight several unanswered questions relating to the regulation of respiratory electron transport in Shewanella and the central role(s) of the tetrahaem-containing quinol dehydrogenase CymA in that process.
