Transcriptional regulator NadR.

Nicotinate phosphoribosyltransferase; Catalyzes the synthesis of beta-nicotinate D-ribonucleotide from nicotinate and 5-phospho-D-ribose 1-phosphate at the expense of ATP; Belongs to the NAPRTase family.

Nicotinate-nucleotide pyrophosphorylase [carboxylating] (quinolinate phosphoribosyltransferase [decarboxylating]) (QAPRTase); Belongs to the NadC/ModD family.

Acid phosphatase SurE (Stationary-phase survival protein SurE); Nucleotidase with a broad substrate specificity as it can dephosphorylate various ribo- and deoxyribonucleoside 5'-monophosphates and ribonucleoside 3'-monophosphates with highest affinity to 3'-AMP. Also hydrolyzes polyphosphate (exopolyphosphatase activity) with the preference for short-chain-length substrates (P20-25). Might be involved in the regulation of dNTP and NTP pools, and in the turnover of 3'-mononucleotides produced by numerous intracellular RNases (T1, T2, and F) during the degradation of various RNAs.

MazG protein.

Protein UshA precursor [Includes: UDP-sugar hydrolase (UDP-sugar diphosphatase) (UDP-sugar pyrophosphatase); 5'-nucleotidase (5'-NT)]; Belongs to the 5'-nucleotidase family.

NADH pyrophosphatase.

RecA protein (Recombinase A); 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.

2-acylglycerophosphoethanolamine acyl transferase/acyl carrier protein synthase; Plays a role in lysophospholipid acylation. Transfers fatty acids to the 1-position via an enzyme-bound acyl-ACP intermediate in the presence of ATP and magnesium. Its physiological function is to regenerate phosphatidylethanolamine from 2-acyl-glycero-3- phosphoethanolamine (2-acyl-GPE) formed by transacylation reactions or degradation by phospholipase A1.
