| Research Abstract |
A gene encoding a pantothenate kinase (CoaA) which is a key enzyme in coenzyme A biosynthetic pathway has been identified in a thermoacidophilic archaeon. The archaeal CoaA belongs to a prokaryotic type I CoaA and is not governed by feedback inhibition by CoA and its thioesters, although prokaryotic type I CoaAs are generally inhibited by the CoA species. Therefore, CoA biosynthetic pathways in the archaea belonging to the order Thermoplasmatales which has the type I CoaA are not regulated at CoaA step.
