Tyrosinase is a type-3 copper protein with six conserved histidine residues within the copper-binding sites. It participates in mollusk nacre formation. Here, we identified nacreous-layer-specific ...

In the assay of tyrosinase inhibitory activity, we set up four groups: sample group, sample blank group, negative group, and blank group. First, sample solution (70 μL) was added to the sample and ...

The effects of normal and cancer blood on the aerobic oxidation of tyrosine in the presence of tyrosinase were investigated as a ... shaking, etc.; (2) the enzyme preparation; (3) the substrate; (4) ...

It is a unique member of the plastic family as it can be broken down into its constituent units (or monomers) by PETases, which are enzymes that degrade PET. Until now, scientists have discovered ...

Three possible hypotheses may be advanced to explain the reduction of melanin formation: absence of the melanin-forming enzyme, tyrosinase; absence or decrease of the melanin precursor ...

Engineered enzymes are poised to have transformative impacts across applications in energy, materials, biotechnology, and medicine. Recently, machine learning has emerged as a useful tool for ...

Rubisco is the enzyme responsible for carbon fixation in plants, algae and many bacteria. A screen of a comprehensive library of rubisco variants (each with a different single-amino-acid mutation ...

Temperature affects enzyme-catalysed reactions by influencing the rate at which they occur. For a reaction to occur between an enzyme and substrate the two molecules need to collide. At lower ...
