ADH5 (chi-ADH/FDH) gene structure was characterized: it is composed of nine exons and eight introns, has a CpG-island promoter lacking TATA and CAAT boxes (consistent with ubiquitous expression), and a 1.5-kb upstream fragment drives reporter transcription in CV-1 cells. Two major transcription start points were identified by primer extension. |

ADH5/FDH transcription is driven by Sp1 binding to two core cis-elements (−22 bp to +22 bp) in the minimal promoter; Sp3 and Sp4 repress transcription by competing with Sp1 for these same elements without activating transcription themselves. |

GSNOR deficiency leads to S-nitrosylation and proteasomal degradation of the DNA repair protein O6-alkylguanine-DNA alkyltransferase (AGT/MGMT), impairing repair of carcinogenic O6-alkylguanines and promoting hepatocarcinogenesis; these effects are abolished in GSNOR/iNOS double-knockout mice, placing iNOS upstream of GSNOR-regulated S-nitrosylation. |

GSNOR is itself subject to inhibitory S-nitrosation at conserved non-zinc-coordinating cysteine residues; nitrosation reduces catalytic activity (reversible by DTT), promotes thermal aggregation and increased polydispersity, and alters the shape of substrate/coenzyme binding pockets as shown by HDX-MS. Site-directed mutagenesis of specific cysteines reduces sensitivity to nitrosating agents. |
