In molecular biology, the SR1 RNA is a small RNA (sRNA) produced by species of Bacillus and closely related bacteria . It is a dual-function RNA which acts both as a protein -coding RNA and as a regulatory sRNA.

44-421: A release of chemical free energy, some of which is lost as heat , but the rest of which is used to drive the synthesis of adenosine triphosphate (ATP). This molecule acts as a way for the cell to transfer the energy released by catabolism to the energy-requiring reactions that make up anabolism . Catabolism is a destructive metabolism and anabolism is a constructive metabolism. Catabolism, therefore, provides

SR1 RNA binds to complementary stretches of ahrC mRNA (also known as argR and inhibits translation . AhrC endodes an arginine repressor protein which represses synthesis of arginine biosynthetic enzymes and activates arginine catabolic enzymes via regulation of
66-438: Is the breaking-down aspect of metabolism , whereas anabolism is the building-up aspect. Cells use the monomers released from breaking down polymers to either construct new polymer molecules or degrade the monomers further to simple waste products, releasing energy. Cellular wastes include lactic acid , acetic acid , carbon dioxide , ammonia , and urea . The formation of these wastes is usually an oxidation process involving
77-399: Is the set of metabolic pathways that breaks down molecules into smaller units that are either oxidized to release energy or used in other anabolic reactions. Catabolism breaks down large molecules (such as polysaccharides , lipids , nucleic acids , and proteins ) into smaller units (such as monosaccharides , fatty acids , nucleotides , and amino acids , respectively). Catabolism
88-440: The chemical energy necessary for the maintenance and growth of cells. Examples of catabolic processes include glycolysis , the citric acid cycle , the breakdown of muscle protein in order to use amino acids as substrates for gluconeogenesis , the breakdown of fat in adipose tissue to fatty acids , and oxidative deamination of neurotransmitters by monoamine oxidase . There are many signals that control catabolism. Most of
99-579: The known signals are hormones and the molecules involved in metabolism itself. Endocrinologists have traditionally classified many of the hormones as anabolic or catabolic, depending on which part of metabolism they stimulate. The so-called classic catabolic hormones known since the early 20th century are cortisol , glucagon , and adrenaline (and other catecholamines ). In recent decades, many more hormones with at least some catabolic effects have been discovered, including cytokines , orexin (known as hypocretin ), and melatonin . The word catabolism
110-435: The rocABC and rocDEF operons . In addition to acting as a sRNA, SR1 also encodes a small peptide, SR1P. SR1P binds to glyceraldehyde-3-phosphate dehydrogenase (GapA) and stabilises the gapA operon mRNAs. SR1 expression is regulated by CcpA and CcpN. This molecular biology article is a stub .
