Rl. Charlebois et al., EVOLUTIONARY ANALYSIS OF THE HISCGAB(D)FDEHI GENE-CLUSTER FROM THE ARCHAEON SULFOLOBUS-SOLFATARICUS P2, Journal of bacteriology, 179(13), 1997, pp. 4429-4432
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 o
peron. Results of phylogenetic analysis of the coding regions in the p
utative operon give conflicting evolutionary histories for individual
his genes.
