OC Bacteria; Spirochaetes; Spirochaetales; Brachyspiraceae; Brachyspira. OX NCBI_TaxID=565034; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RX PubMed=19262690; DOI=10.1371/journal.pone.0004641; RA Bellgard M.I., Wanchanthuek P., La T., Ryan K., Moolhuijzen P., RA Albertyn Z., Shaban B., Motro Y., Dunn D.S., Schibeci D., Hunter A., RA Barrero R., Phillips N.D., Hampson D.J.; RT "Genome sequence of the pathogenic intestinal spirochete Brachyspira RT hyodysenteriae reveals adaptations to its lifestyle in the porcine RT large intestine."; RL PLoS ONE 4:E4641-E4641(2009). CC -!- FUNCTION: Plays an important role in the de novo pathway of purine CC nucleotide biosynthesis (By similarity). CC -!- CATALYTIC ACTIVITY: GTP + IMP + L-aspartate = GDP + phosphate + CC N(6)-(1,2-dicarboxyethyl)-AMP. CC -!- COFACTOR: Binds 1 magnesium ion per subunit (By similarity). CC -!- PATHWAY: Purine metabolism; AMP biosynthesis via de novo pathway; CC AMP from IMP: step 1/2. CC -!- SUBUNIT: Homodimer (By similarity). CC -!- SUBCELLULAR LOCATION: Cytoplasm (By similarity). CC -!- SIMILARITY: Belongs to the adenylosuccinate synthetase family.
