title: Evolutionary analysis of the hisCGABdFDEHI gene cluster from the archaeon Sulfolobus solfataricus P2.
abstract: While sequencing the genome of the archaeon Sulfolobus solfataricus P2, we found an 8,313-bp sequence containing a cluster of nine histidine biosynthesis genes in an order different from that of any known his operon. Results of phylogenetic analysis of the coding regions in the putative operon give conflicting evolutionary histories for individual his genes.
