Abstract

Two structural genes for the Thermus thermophilus elongation factor Tu (tuf) were identified by cross-hybridization with the tufA gene from E. coli. The sequence of one of these tuf genes, localized on a 6.6 kb Bam HI fragment, was determined and confirmed by partial protein sequencing of an authentic elongation factor Tu from T. thermophilus HB8. Expression of this tuf gene in E. coli minicells provided a low amount of immuno-precipitable thermophilic EF-Tu. Affinity labeling of the T. thermophilus EF-Tu and sequence comparison with homologous proteins from other organisms were used to identify the guanosine-nucleotide binding domain.
