    1.1.1.35 | evolution |
based on the chain length of the substrates, the HAD family is divided into three subclasses: 3-hydroxyacyl-CoA dehydrogenases (HADs), long-chain 3-hydroxyacyl-CoA dehydrogenases (LCHADs) and short-chain 3-hydroxyacyl-CoA dehydrogenases (SCHADs). HADs are soluble dimeric enzymes that exhibit substrate specificity for an acyl-chain length of C4-C10 and are previously referred to as short-chain HADs |

two (S)-3-hydroxyacyl-CoA dehydrogenase/enoyl-CoA hydratases, H16_A0461/FadB' and H16_A1526/FadB1, are involved in the FA degradation in Ralstonia eutropha H16. FadB' and FadB1 possess an enoyl-CoA hydratase activity, catalyzing hydrogenation of the unsaturated enoyl coenzyme A (CoA), and a 3-hydroxyacyl-CoA dehydrogenase activity, i.e. oxidation of the hydroxyl group into a keto group using one NAD+ molecule |

a null mutant of fadB2 shows no significant differences from the wild-type strain with regard to lipid composition, utilization of different fatty acid carbon sources and tolerance to various stresses |

mice lacking SCHAD, hadh-/-, display a lower body weight and a reduced fat mass in comparison with hadh+/+ mice under high-fat diet conditions, presumably due to an impaired fuel efficiency, the loss of acylcarnitines via the urine, and increased body temperature. Food intake, total energy expenditure, and locomotor activity are not altered in knockout mice |

mutantions with attenuated interactions on the dimerization interface significantly decrease the enzyme activity compared to the wild-type. Such reduced activities are in consistency with the reduced ratios of the catalytic intermediate formation. Further molecular dynamics simulations results reveal that the alteration of the dimerization interface will increase the fluctuation of a distal region that plays an important role in the substrate binding. The increased fluctuation decreases the stability of the catalytic intermediate formation, and therefore the enzymatic activity is attenuated |

mutations in HADH cause hyperinsulinemic hypoglycemia that is precipitated by protein in a similar manner to the hyperinsulinism/hyperammonemia (HI/HA) syndrome, which is caused by mutations in the GLUD1 gene, encoding the enzyme glutamate dehydrogenase (GDH), suggesting a link between mitochondrial fatty acid oxidation, amino acid metabolism, and insulin secretion, clinical phenotypes, overview |
