EC 1.1.1.41.RNA, Messenger: RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.Aldehyde Oxidoreductases: Oxidoreductases that are specific for ALDEHYDES.Phosphoadenosine Phosphosulfate: 3'-Phosphoadenosine-5'-phosphosulfate.

The soluble form is present mainly in ERYTHROCYTES and is involved in the reduction of METHEMOGLOBIN. The membrane-bound form of the enzyme is found primarily in the ENDOPLASMIC RETICULUM and outer mitochondrial membrane, where it participates in the desaturation of FATTY ACIDS; CHOLESTEROL biosynthesis and drug metabolism. A deficiency in the enzyme can result in METHEMOGLOBINEMIA.Nitrite Reductases: A group of enzymes that oxidize diverse nitrogenous substances to yield nitrite.

  • Although circulating cortisol concentrations are invariably normal in patients with obesity and metabolic syndrome ( 1 ), in vitro, in vivo, and clinical studies over the last decade have collectively shown the importance of local generation of cortisol, via 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) in liver and fat, in mediating many facets of the metabolic syndrome ( 2 ).
