13. tmRNAs that encode proteolysis-inducing tags are found in all known bacterial genomes: A two-piece tmRNA functions in Caulobacter
A general mechanism in bacteria to rescue stalled ribosomes and to clear the cell of incomplete polypeptides involves an RNA species, tmRNA (SsrA), which functions as both a tRNA and an mRNA. This RNA encodes a peptide tag that is incorporated at the end of the aberrant polypeptide and targets it for proteolysis. We have identified a circularly permuted vers

14. Convergent evolution of antifreeze glycoproteins in Antarctic notothenioid fish and Arctic cod
Antarctic notothenioid fishes and several northern cods are phylogenetically distant (in different orders and superorders), yet produce near-identical antifreeze glycoproteins (AFGPs) to survive in their respective freezing environments. AFGPs in both fishes are made as a family of discretely sized polymers composed of a simple glycotripeptide monomeric repe

15. Molecular Epidemiology of Metronidazole Resistance in a Population of Trichomonas vaginalis Clinical Isolates
Trichomonas vaginalis, the causative agent for human trichomoniasis, is a problematic sexually transmitted disease mainly in women, where it may be asymptomatic or cause severe vaginitis and cervicitis. Despite its high prevalence, the genetic variability and drug resistance characteristics of this organism are poorly understood. To address these issues, gen
