Cytochrome B; Component of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex), which is a respiratory chain that generates an electrochemical potential coupled to ATP synthesis.

DNA polymerase I; Identified by match to protein family HMM PF00476; match to protein family HMM PF01367; match to protein family HMM PF02739; match to protein family HMM TIGR00593.

Chaperone protein HtpG (Heat shock protein htpG) (High temperatureprotein G); Molecular chaperone. Has ATPase activity.

Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.

Identified by match to protein family HMM PF00149.

Ribosomal protein S3; Binds the lower part of the 30S subunit head. Binds mRNA in the 70S ribosome, positioning it for translation; Belongs to the universal ribosomal protein uS3 family.

Molybdopterin biosynthesis protein MoeB; Identified by match to protein family HMM PF00899; match to protein family HMM PF05237.

Acyl carrier protein.

NADH dehydrogenase i, a subunit; NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be ubiquinone. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient; Belongs to the complex I subunit 3 family.
