RC STRAIN=ATCC BAA-835 / Muc; RX PubMed=21390229; DOI=10.1371/journal.pone.0016876; RA van Passel M.W., Kant R., Zoetendal E.G., Plugge C.M., Derrien M., RA Malfatti S.A., Chain P.S., Woyke T., Palva A., de Vos W.M., Smidt H.; RT "The genome of Akkermansia muciniphila, a dedicated intestinal mucin RT degrader, and its use in exploring intestinal metagenomes."; RL PLoS ONE 6:E16876-E16876(2011). CC -!- FUNCTION: Catalyzes the condensation of pantoate with beta-alanine CC in an ATP-dependent reaction via a pantoyl-adenylate intermediate. CC {ECO:0000255|HAMAP-Rule:MF_00158}. CC -!- CATALYTIC ACTIVITY: ATP + (R)-pantoate + beta-alanine = AMP + CC diphosphate + (R)-pantothenate. {ECO:0000255|HAMAP-Rule:MF_00158}. CC -!- PATHWAY: Cofactor biosynthesis; (R)-pantothenate biosynthesis; CC (R)-pantothenate from (R)-pantoate and beta-alanine: step 1/1. CC {ECO:0000255|HAMAP-Rule:MF_00158}. CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00158}. CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00158}. CC -!- MISCELLANEOUS: The reaction proceeds by a bi uni uni bi ping pong CC mechanism. {ECO:0000255|HAMAP-Rule:MF_00158}. CC -!- SIMILARITY: Belongs to the pantothenate synthetase family. CC {ECO:0000255|HAMAP-Rule:MF_00158}.
