Glutamate dehydrogenases (GDHs) are a broadly distributed group of enzymes that catalyse the reversible oxidative deamination of glutamate to ketoglutarate and ammonia [1]. The structure of GDH from Mycobacterium smegmatis revealed that it has a long N- and C-terminal segments flanking the catalytic core, comprising several domains. The flexible N-terminal domain comprises ACT-like and PAS-type domains which could act as metabolic sensors for allosteric regulation [2]. This entry represents the helical C-terminal domain.	Domain

Glutamate dehydrogenases (GDHs) are a broadly distributed group of enzymes that catalyse the reversible oxidative deamination of glutamate to ketoglutarate and ammonia [1]. The structure of GDH from Mycobacterium smegmatis revealed that it has a long N- and C-terminal segments flanking the catalytic core, comprising several domains. The flexible N-terminal domain comprises three ACT-like (ACT1-3) and PAS-type domains which could act as metabolic sensors for allosteric regulation [2]. This entry represents ACT3 domain.	Domain

This entry represents the catalytic domain of several proteins which are closely related to NAD-glutamate dehydrogenase found in Streptomyces clavuligerus. Glutamate dehydrogenases (GDHs) are a broadly distributed group of enzymes that catalyse the reversible oxidative deamination of glutamate to ketoglutarate and ammonia [1]. The structure of GDH from Mycobacterium smegmatis revealed that it has long N- and C-terminal segments flanking the catalytic core which provide dimer-like interactions between pairs of monomers [2]. The N-terminal segment is flexible and contains ACT-like and PAS-type domains that may play a role as metabolic sensors for allosteric regulation [2].	Domain
