  • Bacteria
  • The stringent response, also called stringent control, is a stress response of bacteria and plant chloroplasts in reaction to amino-acid starvation, fatty acid limitation, iron limitation, heat shock and other stress conditions. (wikipedia.org)
  • In other bacteria, the stringent response is mediated by a variety of RelA/SpoT Homologue (RSH) proteins, with some having only synthetic, or hydrolytic or both (Rel) activities. (wikipedia.org)
  • reaction
  • On the other hand, each enzymatic activity (Condensation reaction, Reduction Reaction, Dehydration reaction) is found as a discrete protein in type II systems. (wikipedia.org)
  • Molecular
  • In recent years, the molecular organization of the plant fatty acid synthetases has been examined in extracts from various plant tissues, and in all cases was found to be nonassociated and similar to the prokaryotic type of E . coli (1, 2, 3). (springer.com)
  • Nature 452(7183):108-11 Trigger Factor in Complex with the Ribosome forms a Molecular Cradle for Nascent Proteins. (wikipedia.org)
  • Complexes
  • The lipoyl group transfers acyl groups in 2-oxoacid dehydrogenase complexes, and methylamine group in the glycine cleavage complex or glycine dehydrogenase. (wikipedia.org)
  • Specifically focusing on various ribosomal complexes involved in co-translational protein processing, folding, and targeting. (wikipedia.org)
  • starvation
  • During catabolic states (eg, starvation, infections, burns), more protein may be used (because body tissues are broken down) than is absorbed, resulting in a net loss of protein (negative nitrogen balance). (encognitive.com)
  • multifunctional
  • They are characterized by being composed of either large multifunctional polypeptides in the case of type I or consisting of discretely expressed mono-functional proteins in the type II system. (biochemj.org)
  • genes
  • RhlA and RhlB respectively, are expected to form a complex because of the operonic nature of the genes which encode these two proteins and because both proteins are necessary for production of rhamnolipids. (wikipedia.org)
  • chain
  • Furthermore, RhlA preferentially interacts with hydroxyacyl-ACP with an acyl chain length of ten carbon residues. (wikipedia.org)
