Gramicidin S biosynthesis operon containing the structural genes grsA and grsB has an open reading frame encoding a protein homologous to fatty acid thioesterases
Open accessAbstract
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.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
