The number of flavin-dependent protein encoded genes in the genome (the flavoproteome) is species dependent and can range from 0.1% - 3.5%, with humans having 90 flavoprotein encoded genes. [16] FAD is the more complex and abundant form of flavin and is reported to bind to 75% of the total flavoproteome [ 16 ] and 84% of human encoded ...
If the acyl CoA contains a cis-Δ 3 bond, then cis-Δ 3-Enoyl CoA isomerase will convert the bond to a trans-Δ 2 bond, which is a regular substrate. If the acyl CoA contains a cis-Δ 4 double bond, then its dehydrogenation yields a 2,4-dienoyl intermediate, which is not a substrate for enoyl CoA hydratase.
Fatty acyl-CoA esters are fatty acid derivatives formed of one fatty acid, a 3'-phospho-AMP linked to phosphorylated pantothenic acid (vitamin B 5) and cysteamine. Long-chain acyl-CoA esters are substrates for a number of important enzymatic reactions and play a central role in the regulation of metabolism as allosteric regulators of several ...
The medium chain acyl-CoA dehydrogenase (MCAD) is the best known structure of all ACADs, and is the most commonly deficient enzyme within the class that leads to metabolic disorders in animals. [1] This protein is a homotetramer with each subunit containing roughly 400 amino acids and one equivalent of FAD per monomer.
There are 18 key atoms in isoalloxazine that make up its characteristic three-ring structure. The R-group varies and differentiates various flavins. Riboflavin. Flavins (from Latin flavus, "yellow") refers generally to the class of organic compounds containing the tricyclic heterocycle isoalloxazine or its isomer alloxazine, and derivatives thereof.
NAD + to NADH. FMN to FMNH 2. CoQ to CoQH 2.. Complex I is the first enzyme of the mitochondrial electron transport chain.There are three energy-transducing enzymes in the electron transport chain - NADH:ubiquinone oxidoreductase (complex I), Coenzyme Q – cytochrome c reductase (complex III), and cytochrome c oxidase (complex IV).

The B chain of dipicolinate synthase, an enzyme which catalyses the formation of dipicolinic acid from dihydroxydipicolinic acid [13] Phenylacrylic acid decarboxylase (EC 4.1.1.102), an enzyme which confers resistance to cinnamic acid in yeast [14] Phototropin and cryptochrome, light-sensing proteins [15]
The branched-chain α-ketoacid dehydrogenase complex (BCKDC or BCKDH complex) is a multi-subunit complex of enzymes that is found on the mitochondrial inner membrane. [1] This enzyme complex catalyzes the oxidative decarboxylation of branched, short-chain alpha-ketoacids .
