This enzyme belongs to the family of lyases, to be specific, the hydro-lyases, which cleave carbon-oxygen bonds. CBS is a multidomain enzyme composed of an N-terminal enzymatic domain and two CBS domains. The CBS gene is the most common locus for mutations associated with homocystinuria. [6]
Enzyme activity is a measure of the quantity of active enzyme present and is thus dependent on various physical conditions, which should be specified. It is calculated using the following formula: a = n t = r × V {\displaystyle \mathrm {a} =\mathrm {n} _{\text{t}}=\mathrm {r} \times \mathrm {V} }
CYP2E1 enzyme metabolizes mostly small, polar molecules, including toxic laboratory chemicals such as dimethylformamide, aniline, and halogenated hydrocarbons (see table below). While these oxidations are often of benefit to the body, certain carcinogens and toxins are bioactivated by CYP2E1, implicating the enzyme in the onset of ...
where n is the number of monomers in the polymer chain, though a trace amount of the PET breaks down instead to bis(2-hydroxyethyl) terephthalate (BHET). [1] PETases can also break down PEF-plastic ( polyethylene-2,5-furandicarboxylate ), which is a bioderived PET replacement, into the analogous MHEF .
In particular, amino acid substitutions that change the electric charge of the enzyme are simple to identify by gel electrophoresis, and this forms the basis for the use of isozymes as molecular markers. To identify isozymes, a crude protein extract is made by grinding animal or plant tissue with an extraction buffer, and the components of ...
Glutathione peroxidase (GPx) (EC 1.11.1.9) is the general name of an enzyme family with peroxidase activity whose main biological role is to protect the organism from oxidative damage. [2] The biochemical function of glutathione peroxidase is to reduce lipid hydroperoxides to their corresponding alcohols and to reduce free hydrogen peroxide to ...
Beta-hexosaminidase subunit beta is an enzyme that in humans is encoded by the HEXB gene. [5] [6] [7]Hexosaminidase B is the beta subunit of the lysosomal enzyme beta-hexosaminidase that, together with the cofactor GM2 activator protein, catalyzes the degradation of the ganglioside GM2, and other molecules containing terminal N-acetyl hexosamines.
Acetolactate synthase is catalytic enzyme involved in the biosynthesis of various amino acids. This enzyme has the Enzyme Commission Code is 2.2.1.6, which means that the enzyme is a transketolase or a transaldolase, which is classified under the transferases that transfer aldehyde or ketone residues.
