gltb_C. This domain is found at the C-terminus of the large subunit (gltB) of glutamate synthase (GltS). GltS encodes a complex iron-sulfur flavoprotein that catalyzes the synthesis of L-glutamate from L-glutamine and 2-oxoglutarate. It requires the transfer of ammonia and electrons among three distinct active centers that carry out L-Gln hydrolysis, conversion of 2-oxoglutarate into L-Glu, and electron uptake from a donor. These catalytic sites appear to occur in other domains within the protein, and not the domain in this CD. This particular domain has no known function, but it likely has a structural role as it interacts with the amidotransferase and FMN-binding domains of gltS.

GXGXG domain. This domain of unknown function is found at the C-terminus of the large subunit (gltB) of glutamate synthase (GltS), in subunit C of tungsten formylmethanofuran dehydrogenase (FwdC) and in subunit C of molybdenum formylmethanofuran dehydrogenase (FmdC). It is also found in a primarily archeal group of proteins predicted to encode part of the large subunit of GltS. It is characterized by a repeated GXXGXXXG motif. GltS is a complex iron-sulfur flavoprotein that catalyzes the synthesis of L-glutamate from L-glutamine and 2-oxoglutarate. It requires the transfer of ammonia and electrons among three distinct active centers that carry out L-Gln hydrolysis, conversion of 2-oxoglutarate into L-Glu, and electron uptake from a donor. These catalytic sites occur in other domains within the protein or or encoded by separate genes, and are not present in the domain in this CD. FwdC and FmdC are reversible ion pumps that catalyze the formylation and deformylation of methanofuran in hyperthermophiles and bacteria. They require the presence of either tungstun (FwdC) or molybdenum (FmdC). The specific function of this domain also remains unidentified in the formylmethanofuran dehydrogenases.

Conserved region in glutamate synthase; This family represents a region of the glutamate synthase protein. This region is expressed as a separate subunit in the glutamate synthase alpha subunit from archaebacteria, or part of a large multidomain enzyme in other organizms. The aligned region of these proteins contains a putative FMN binding site and Fe-S cluster.

Glutamate synthase (GltS) FMN-binding domain. GltS is a complex iron-sulfur flavoprotein that catalyzes the reductive synthesis of L-glutamate from 2-oxoglutarate and L-glutamine via intramolecular channelling of ammonia, a reaction in the plant, yeast and bacterial pathway for ammonia assimilation. It is a multifunctional enzyme that functions through three distinct active centers, carrying out L-glutamine hydrolysis, conversion of 2-oxoglutarate into L-glutamate, and electron uptake from an electron donor.

(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
