The nucleotide sequence has been determined for a twelve-gene operon of Escherichia coli
designated the hyf operon (hyfABCDEFGHIR-focB). The hyf operon is located at 55.8-56.0 …

In‐frame deletions were introduced into each of the eight genes of the hyc operon coding for
products required for the formation of the formate hydrogenlyase (FHL) system. The …

The hyf locus (hyfABCDEFGHIJ-hyfR-focB) of Escherichia coli encodes a putative 10-
subunit hydrogenase complex (hydrogenase-4 [Hyf]); a potential σ54-dependent …

Under anaerobic conditions, Escherichia coli can carry out a mixed-acid fermentation that
ultimately produces molecular hydrogen. The enzyme directly responsible for hydrogen …

On the basis of hyf-lacZ fusion studies, the hyf operon of Escherichia coli, noted for encoding
the fourth hydrogenase isoenzyme (HYD4), is not expressed at a significant level in a wild …

Through complementation of a trans‐acting regulatory mutation a gene has been cloned
whose product is required for the formate induction of the anaerobic expression of the …

The hydA locus of Escherichia coli is known to encode some function necessary for
formation of hydrogenase activity. The locus contains two open reading frames, hydN and …

The cellular contents of the nickel-containing, membrane-bound hydrogenase isoenzymes 1
and 2 (hydrogenases 1 and 2) were analyzed by crossed immunoelectrophoresis. Their …

The hyc operon of Escherichia coli encodes the H2-evolving hydrogenase 3 (Hyd-3)
complex that, in conjunction with formate dehydrogenase H (Fdh-H), constitutes a …

The 58/59 min region of the Escherichia coli chromosome contains two divergently oriented
gene clusters coding for proteins with a function in hydrogenase formation. One cluster (the …
