New mammalian selenocysteine-containing proteins identified with an algorithm that searches for selenocysteine insertion sequence elements.
Mammalian selenium-containing proteins identified thus far contain selenium in the form of a selenocysteine residue encoded by UGA. These proteins lack common amino acid sequence motifs, but 3'-untranslated regions of selenoprotein genes contain a common stem-loop structure, selenocysteine insertion sequence (SECIS) element, that is necessary for decoding UGA as selenocysteine rather than a sto...
متن کاملEvolutionary progression at synaptic connections made by identified homologous neurones.
A comparative ultrastructural study of photoreceptor synapses formed upon homologous postsynaptic neurones in insects has been made by using serial-section electron microscopy in representative Diptera from a monophyletic series of 14 families. At all of the synaptic contacts there is a presynaptic dense bar, surmounted in phylogenetically more recent families by a presynaptic platform. Opposit...
متن کاملCell death induction by Streptococcus pyogenes in four types of malignant cell lines
Abstract Background: The interest in using bacteria as anti- cancer therapeutic agents dates back to the end of the19th century. Some bacteria like Salmonella and Listeria replicate effectively inside malignant cell lines and suppress their growth. The bacterium Streptococcus pyogenes has become medically famous as a flesh-eating pathogen since mid-1980s. It is the causative agent of a life...
متن کاملMutations Involving an Insertion Sequence
Escherichia coli K12 strain x342LD requires two mutations in the bgl (@-glucosidase) operon, bglRo + bglR+ and excision of IS103 from within bglF, in order to utilize salicin. In growing cells the two mutations occur at rates of 4 X lo-* per cell division and <2 X 10”‘ per cell division, respectively. In 2-3-week-old colonies on MacConkey salicin plates the double mutants occur at frequencies o...
متن کاملInsertion sequence diversity in archaea.
Insertion sequences (ISs) can constitute an important component of prokaryotic (bacterial and archaeal) genomes. Over 1,500 individual ISs are included at present in the ISfinder database (www-is.biotoul.fr), and these represent only a small portion of those in the available prokaryotic genome sequences and those that are being discovered in ongoing sequencing projects. In spite of this diversi...
