Comments
[?]
| FUNCTION | Catalyzes the condensation of pantoate with beta-alanine in an ATP-dependent reaction via a pantoyl-adenylate intermediate. |
| CATALYTIC ACTIVITY | Reaction=(R)-pantoate + ATP + beta-alanine = (R)-pantothenate + AMP + diphosphate + H(+); Xref=Rhea:RHEA:10912, ChEBI:CHEBI:15378, ChEBI:CHEBI:15980, ChEBI:CHEBI:29032, ChEBI:CHEBI:30616, ChEBI:CHEBI:33019, ChEBI:CHEBI:57966, ChEBI:CHEBI:456215; EC=6.3.2.1; |
| PATHWAY | Cofactor biosynthesis; (R)-pantothenate biosynthesis; (R)- pantothenate from (R)-pantoate and beta-alanine: step 1/1. |
| SUBUNIT | Homodimer. |
| SUBCELLULAR LOCATION | Cytoplasm. |
| MISCELLANEOUS | The reaction proceeds by a bi uni uni bi ping pong mechanism. |
| SIMILARITY | Belongs to the pantothenate synthetase family. |
