What are the enzymes in alpha-ketoglutarate dehydrogenase complex?

α-KGDC is a complex consisting of multiple copies of three enzymes: α-ketoglutarate dehydrogenase (E1), dihydrolipoamide succinyltransferase (E2), and dihydrolipoamide dehydrogenase (E3).

What other cofactors or co substrates does the α ketoglutarate dehydrogenase complex require to function?

What do the PDH complex and α‑ketoglutarate dehydrogenase complex have in common? Both have 3 specific enzymatic activities catalyzed by different subunits. The α‑ketoglutarate dehydrogenase complex requires the cosubstrate CoA to convert α‑ketoglutarate to succinyl CoA.

Which cofactor is required by the E1 complex in α kg dehydrogenase?

thiamine pyrophosphate (TPP)
The E1 enzyme is encoded by the OGDH gene and is the proper dehydrogenase catalyzing the decarboxylation of α-KG requiring thiamine pyrophosphate (TPP) as cofactor.

What enzyme converts alpha-ketoglutarate to succinyl CoA?

complex α-ketoglutarate dehydrogenase complex
13.2. An enzyme complex α-ketoglutarate dehydrogenase complex catalyzes oxidative decarboxylation of α-ketoglutarate into succinyl CoA and NADH using acetyl CoA and NAD+ (2; Fig. 13.8). This enzyme requires the cofactor thiamine pyrophosphate for catalytic activity.

What is the alpha ketoglutarate dehydrogenase complex?

The alpha-ketoglutarate dehydrogenase complex (KGDHC) is an important mitochondrial constituent, and deficiency of KGDHC is associated with a number of neurological disorders. KGDHC is composed of three proteins, each encoded on a different and well-characterized gene.

Can alpha-ketoglutarate dehydrogenase regulate metabolic flux through the Krebs cycle?

Alpha-ketoglutarate dehydrogenase (α-KGDH) is a highly regulated enzyme, which could determine the metabolic flux through the Krebs cycle.

What enzyme catalyzes the conversion of keto-ketoglutarate to ketamine?

The enzyme α-ketoglutarate dehydrogenase catalyzes this conversion. This conversion is quite complex and requires FIVE vitamin derived cofactors to complete.

How many cofactors are needed to convert pyruvate to ketoglutarate?

This conversion is quite complex and requires FIVE vitamin derived cofactors to complete. This is very similar to that for the pyruvate dehydrogenase enzyme complex.. in fact the mechanism and overall enzyme structures are very similar… the only difference – this one catalyses the decarboxylation of α-ketoglutarate instead of pyruvate.
