Abstract

The DNA sequence of about 5.9 kilobase pairs (kbp) of the gramicidin S biosynthesis operon (grs) was determined. Three open reading frames were identified; the corresponding genes, called grsT, grsA, and grsB, were found to be organized in one transcriptional unit, not two as previously reported (M. Krause and M. A. Marahiel, J. Bacteriol. 170:4669-4674, 1988). The entire nucleotide sequence of grsA, coding for the 126.663-kilodalton gramicidin S synthetase 1, grsT, encoding a 29.191-kilodalton protein of unknown function, and 732 bp of the 5' end of grsB, encoding the gramicidin S synthetase 2, were determined. A single initiation site of transcription 81 bp upstream of the grsT initiation condon GTG was identified by high-resolution S1 mapping studies. The sequence of the grsA gene product showed a high degree of homology to the tyrocidine synthetase 1 (TycA protein), and that of grsT exhibited a significant degree of homology to vertebrate fatty acid thioesterases.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.
