Membrane-bound hydrogenase and sulfur reductase of the hyperthermophilic and acidophilic archaeon Acidianus ambivalens

Laska, S.; Lottspeich, F.; Kletzin, A.; Microbiology 149, 2357-2371 (2003)

Data extracted from this reference:

Cloned(Commentary)
Commentary
Organism
the SR gene cluster encompasses five ORFs with a total length of 7389 bp. The sreA gene encodes the 110000 Da subunit of SR. sreB encodes an FeS protein, sreC encodes a hydrophobic protein with 10 predicted transmembrane helices. The sreD gene encodes a putative hydrophilic FeS protein with 26 cysteine residues and of unknown cluster composition. The sreE gene encodes a protein with similarity to reductase assembly proteins
