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 .
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} }
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 ...
The biochemical pathways required to utilize glucose as a carbon and energy source are highly conserved from bacteria to humans. PGM1 is an evolutionarily conserved enzyme that regulates one of the most important metabolic carbohydrate trafficking points in prokaryotic and eukaryotic organisms, catalyzing the bi-directional interconversion of glucose 1-phosphate (G-1-P) and glucose 6-phosphate ...
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 ...
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]
Tryptophan 2,3-dioxygenase is a heme-containing cytosolic enzyme encoded by gene TDO2. [5] Crystallographic studies of Xanthomonas campestris TD) [13] and Ralstonia metallidurans TDO) [16] have revealed that their structures are essentially identical and are intimately associated homotetrameric enzymes. [17]
