Gene Group (FlyBase)
PEPTIDYL-CYSTEINE S-NITROSYLASES -
Peptidyl-cysteine S-nitrosylases are transferases that are involved in the transfer of nitric oxide group to a sulfur atom within a cysteine residue of a protein.
GLYCERALDEHYDE 3 PHOSPHATE DEHYDROGENASES -
Glyceraldehyde-3-phosphate dehydrogenase is a key enzyme in the glycolytic pathway, which is responsible for converting glucose to pyruvate with the concomitant synthesis of ATP. (Adapted from FBrf0048676.)
Phenotypic Description (Red Book; Lindsley and Zimm 1992)
Gapdh1: Glyceraldehyde dehydrogenase 1
One of two genes (Gapdh1 and Gapdh2) that code for the enzyme glyceraldehyde-3-phosphate dehydrogenase [G3PD (EC.1.2.12)]. These genes are expressed in almost all cells, especially those that undergo a high rate of glycolysis.

Model Confidence:
  • Very high (pLDDT > 90)
  • Confident (90 > pLDDT > 70)
  • Low (70 > pLDDT > 50)
  • Very low (pLDDT < 50)

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

          Identified with: GH12586 <up>FlyBase curator comment: EST subsequently found to be chimeric</up>.

          At least a substantial fraction of three glycolytic enzymes of flight muscle cells are found colocalised at the Z-discs and M-lines, glycolytic enzyme colocalisation is interdependent. Localisation of Gapdh1, Gapdh2 and Ald at the Z-discs and M-lines requires the presence of at least Gpdh at the Z-discs and M-lines.

          EST GH12586 is chimeric; the 5' portion (AI134984) corresponds to part of CG4461, the 3' portion (BG632702) corresponds to part of Gapdh1.

          The synergistic effects of the Adh locus, or a tightly linked locus, on the quantities of the Mdh1, Gpdh, Pgm, Idh, Men and Gapdh1 gene products in D.melanogaster derived from an African population has been determined.

          The melanogaster and takahashi subgroups of the melanogaster group have small and large subunits of Gapdh, while another 28 species (in 15 subgroups) studied were found to have only either the large or the small subunit of Gapdh.

          Gapdh1 and Gapdh2 RNA expression has been studied.

          One of two genes (Gapdh1 and Gapdh2) that code for the enzyme glyceraldehyde-3-phosphate dehydrogenase (GAPDH). These genes are expressed in almost all cells, especially those that undergo a high rate of glycolysis.

          The Gapdh1 gene may have been derived from the Gapdh2 gene by retroposition.
