Nicotinate phosphoribosyltransferase; Catalyzes the first step in the biosynthesis of NAD from nicotinic acid, the ATP-dependent synthesis of beta-nicotinate D- ribonucleotide from nicotinate and 5-phospho-D-ribose 1-phosphate. Belongs to the NAPRTase family.

5'-nucleotidase SurE; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.

Putative 5'-nucleotidase; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Belongs to the 5'-nucleotidase family.

DNA strand exchange and recombination protein with protease and nuclease activity; Can catalyze the hydrolysis of ATP in the presence of single- stranded DNA, the ATP-dependent uptake of single-stranded DNA by duplex DNA, and the ATP-dependent hybridization of homologous single-stranded DNAs. It interacts with LexA causing its activation and leading to its autocatalytic cleavage; Belongs to the RecA family.

Conserved hypothetical protein; Homologs of previously reported genes of unknown function.

Apolipoprotein N-acyltransferase 1; Catalyzes the phospholipid dependent N-acylation of the N- terminal cysteine of apolipoprotein, the last step in lipoprotein maturation; Belongs to the CN hydrolase family. Apolipoprotein N- acyltransferase subfamily.

Glycogen phosphorylase; Phosphorylase is an important allosteric enzyme in carbohydrate metabolism. Enzymes from different sources differ in their regulatory mechanisms and in their natural substrates. However, all known phosphorylases share catalytic and structural properties.

Transcription termination factor Rho; Facilitates transcription termination by a mechanism that involves Rho binding to the nascent RNA, activation of Rho's RNA- dependent ATPase activity, and release of the mRNA from the DNA template.

30S ribosomal subunit protein S16; Function of homologous gene experimentally demonstrated in an other organism; structure; Belongs to the bacterial ribosomal protein bS16 family.
