Once the cofactor is added, the enzyme becomes the active “holoenzyme”. Cofactors can either be ions, such as zinc and iron ions, or organic molecules, such as vitamins or vitamin-derived ...

Oxygenases have long been thought to require a cofactor for catalysis. The structure of a vancomycin biosynthetic enzyme in complex with a substrate analog, and with molecular oxygen bound in its ...

Molybdenum is bioavailable as molybdate (MoO 4 2−).Once molybdate enters the cell, it is subsequently incorporated by complex biosynthetic machineries into metal cofactors 1,2.All enzymes that ...

Of these glutathione peroxidase is an enzyme containing four selenium-cofactors that catalyzes the breakdown of hydrogen peroxide and organic hydroperoxides. Glutathione ''S''-transferases show ...

Paving the way for hydrogen from algae enzymes Date: June 3, 2024 Source: Ruhr-University Bochum Summary: Under certain conditions, some algae are able to produce hydrogen -- a much sought-after ...

Feb. 10, 2021 — Scientists describe a novel protein that spurs the post-translational modifications of the amino acid tryptophan to create an enzyme cofactor. This work may lead to the creation ...
