Putative anaerobic allantoin catabolic oxamate carbamoyltransferase; Putative carboxylase.

succinyl-CoA synthetase, beta subunit; Succinyl-CoA synthetase functions in the citric acid cycle (TCA), coupling the hydrolysis of succinyl-CoA to the synthesis of either ATP or GTP and thus represents the only step of substrate-level phosphorylation in the TCA. The beta subunit provides nucleotide specificity of the enzyme and binds the substrate succinate, while the binding sites for coenzyme A and phosphate are found in the alpha subunit. Can use either ATP or GTP, but prefers ATP. It can also function in the other direction for anabolic purposes, and this may be particularly impor [...]

Putative carbamate kinase; Protein involved in arginine biosynthetic process and pyrimidine nucleotide biosynthetic process.

Ureidoglycolate dehydrogenase; AllD plays a pivotal role as a metabolic branch-point enzyme in nitrogen utilization via the assimilation of allantoin. It is able to utilize allantoin as a sole source of nitrogen under anaerobic conditions. Catalyzes the oxidation of ureidoglycolate to oxalurate.

NADH:ubiquinone oxidoreductase, fused CD 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; In the C-terminal section; belongs to the complex I 49 kDa subunit family.

DUF1116 family protein.

Putative uracil/xanthine transporter; Belongs to the xanthine/uracil permease family. Nucleobase:cation symporter-2 (NCS2) (TC 2.A.40) subfamily.

Allantoate amidohydrolase; Involved in the anaerobic nitrogen utilization via the assimilation of allantoin. Catalyzes specifically the hydrolysis of allantoate to yield CO2, NH3 and S- ureidoglycine, which is unstable and readily undergoes a second deamination by S-ureidoglycine aminohydrolase AllE to yield S- ureidoglycolate and NH3. In vivo, the spontaneous release of S-ureidoglycolate and ammonia from S-ureidoglycine appears to be too slow to sustain an efficient flux of nitrogen.

S-ureidoglycine aminohydrolase; Involved in the anaerobic nitrogen utilization via the assimilation of allantoin. Catalyzes the second stereospecific hydrolysis reaction (deamination) of the allantoin degradation pathway, producing S-ureidoglycolate and ammonia from S-ureidoglycine. Belongs to the UGHY family.
