== Function ==
 +
[https://www.uniprot.org/uniprot/COAX_PSEAE COAX_PSEAE] Catalyzes the phosphorylation of pantothenate (Pan), the first step in CoA biosynthesis. Can utilize a wide range of phosphoryl donors other than ATP, and does not discriminate between purine- and pyrimidine-based nucleotides or deoxynucleotides. Is responsible for the resistance of P.aeruginosa to the pantothenamide antibiotics, since it can not bind and phosphorylate these pantothenate analogs.<ref>PMID:16905099</ref>

== Publication Abstract from PubMed ==
 +
Three distinct isoforms of pantothenate kinase (CoaA) in bacteria catalyze the first step in coenzyme A biosynthesis. The structures of the type II (Staphylococcus aureus, SaCoaA) and type III (Pseudomonas aeruginosa, PaCoaA) enzymes reveal that they assemble nearly identical subunits with actin-like folds into dimers that exhibit distinct biochemical properties. PaCoaA has a fully enclosed pantothenate binding pocket and requires a monovalent cation to weakly bind ATP in an open cavity that does not interact with the adenine nucleotide. Pantothenate binds to an open pocket in SaCoaA that strongly binds ATP by using a classical P loop architecture coupled with specific interactions with the adenine moiety. The PaCoaA*Pan binary complex explains the resistance of bacteria possessing this isoform to the pantothenamide antibiotics, and the similarity between SaCoaA and human pantothenate kinase 2 explains the molecular basis for the development of the neurodegenerative phenotype in three mutations in the human protein.
