D. Prangishvili et Hp. Klenk, A HOMOLOG OF THE SMALL-SUBUNIT OF PENICILLIN ACYLASE IS ENCODED IN THE GENOME OF THE EXTREMELY THERMOPHILIC ARCHAEON SULFOLOBUS-SOLFATARICUS, Systematic and applied microbiology, 17(2), 1994, pp. 169-171
A high degree of similarity was found between the sequences of the sma
ll subunit of bacterial penicillin acylases and the amino acid sequenc
e derived from an open reading frame in the genome of the archaeon (ar
chaebacterium) Sulfolobus solfataricus.
