title: Isolation and characterisation of the ylmE homologue of Thermus thermophilus.
abstract: Screening of a Thermus thermophilus genomic library led to the identification of a homologue of the ylmE gene. ylmE is highly conserved in widely divergent organisms from prokaryotes to mammals, suggesting an important, albeit currently unknown, cellular function. The 633 bp gene has a GC content of 69.2% overall and 90% in the third nucleotide position, while the gene product is predicted to be a soluble cytoplasmic protein of 23,441 Da. It belongs to a family of conserved proteins of unknown function and exhibits amino acid identities ranging from 45% to 28% to the Aquifex aeolicus and Saccharomyces cerevisiae family members, respectively. We speculate that the gene product may be involved in a cellular stress response in T. thermophilus.
