Disease relevance of all5345

The gene hetN encodes a putative oxidoreductase that is known to suppress heterocyst differentiation when present on a multicopy plasmid in Anabaena sp. PCC 7120 [1].
Molecular evidence for the aerobic expression of nifJ, encoding pyruvate:ferredoxin oxidoreductase, in cyanobacteria [2].

High impact information on all5345

The thylakoid membrane cytochrome b6-f complex (plastoquinol:oxidized-plastocyanin oxidoreductase, EC 1.10.99.1) catalyzes electron-transfer and proton-translocation reactions essential for oxygenic photosynthesis [3].
Electron microscopy indicates a role of all5345 through all5347 in the normal deposition of the envelope glycolipids [4].
Newly identified Fox- mutants bear transposons in nearby open reading frames (orfs) all5343, all5345-asr5349 and alr5351-alr5358 [4].
Accumulation of GlbN coincided with maximum synthesis of NifH and ferredoxin NADP+ oxidoreductase (PetH or FNR) [5].
