Discovery and characterization of a 5-hydroxymethylfurfural oxidase from Methylovorus sp. strain MP688.
In the search for useful and renewable chemical building blocks, 5-hydroxymethylfurfural (HMF) has emerged as a very promising candidate, as it can be prepared from sugars. HMF can be oxidized to 2,5-furandicarboxylic acid (FDCA), which is used as a substitute for petroleum-based terephthalate in polymer production. On the basis of a recently identified bacterial degradation pathway for HMF, ca...
متن کاملCreating a more robust 5-hydroxymethylfurfural oxidase by combining computational predictions with a novel effective library design
Background HMF oxidase (HMFO) from Methylovorus sp. is a recently characterized flavoprotein oxidase. HMFO is a remarkable enzyme as it is able to oxidize 5-hydroxymethylfurfural (HMF) into 2,5-furandicarboxylic acid (FDCA): a catalytic cascade of three oxidation steps. Because HMF can be formed from fructose or other sugars and FDCA is a polymer building block, this enzyme has gained interest ...
متن کاملCreating Oxidase–Peroxidase Fusion Enzymes as a Toolbox for Cascade Reactions
A set of bifunctional oxidase-peroxidases has been prepared by fusing four distinct oxidases to a peroxidase. Although such fusion enzymes have not been observed in nature, they could be expressed and purified in good yields. Characterization revealed that the artificial enzymes retained the capability to bind the two required cofactors and were catalytically active as oxidase and peroxidase. P...
متن کاملMolecular Characterization and Phylogeny Analysis Based on Sequences of Cytochrome Oxidase gene From Hemiscorpius lepturus of Iran
Abstract: Background: Hemiscorpius lepturus is a medically important scorpion found along the Iranian borders, especially near to Khuzestan Province in the south-west of Iran. This is the only non-buthid scorpion which is potentially lethal in southern Iran and is responsible for severe dermonecrotic scorpionism. OBJECTIVES: In this study, DNA fragment of the mitochondrial cytochrome c oxidase ...
متن کاملEnzymatic Preparation of 2,5-Furandicarboxylic Acid (FDCA)—A Substitute of Terephthalic Acid—By the Joined Action of Three Fungal Enzymes
Enzymatic oxidation of 5-hydroxymethylfurfural (HMF) and its oxidized derivatives was studied using three fungal enzymes: wild-type aryl alcohol oxidase (AAO) from three fungal species, wild-type peroxygenase from Agrocybe aegerita (AaeUPO), and recombinant galactose oxidase (GAO). The effect of pH on different reaction steps was evaluated and apparent kinetic data (Michaelis-Menten constants, ...
