Distribution and phylogenies of enzymes of the Embden-Meyerhof-Parnas pathway from archaea and hyperthermophilic bacteria support a gluconeogenic origin of metabolism [PDF]

open access: yesArchaea, Volume 1, Issue 3, Page 199-221, 2003., 2003
Enzymes of the gluconeogenic/glycolytic pathway (the Embden‐Meyerhof‐Parnas (EMP) pathway), the reductive tricarboxylic acid cycle, the reductive pentose phosphate cycle and the Entner‐Doudoroff pathway are widely distributed and are often considered to be central to the origins of metabolism.

Enzymatic Upgrading of Biomass-Derived Aldoses to Rare Deoxy Ketoses Catalyzed by Transketolase Variants. [PDF]

open access: yesChemSusChem
A sustainable, convenient, scalable, one‐step method for the two‐carbon chain elongation of cheap, biomass‐derived pentoses (l‐arabinose, and 2‐deoxy‐d‐ribose) and a hexose (l‐rhamnose) was developed to produce Cn+2 deoxy ketoses (C‐7 and C‐8) using transketolase, an enzyme catalyzing the irreversible transfer of a ketol group from an α‐ketoacid to an ...

Substrate Induced Movement of the Metal Cofactor between Active and Resting State

open access: yesAngewandte Chemie, Volume 134, Issue 49, December 5, 2022., 2022
Pyruvate dependent Class II aldolases require a ketoacid to induce a metal shift from resting state to active enzyme. This occurs without alterations in the protein structure and might be a common, but to date overlooked, feature in many metalloproteins. Abstract Regulation of enzyme activity is vital for living organisms.

Aroma and color development during the production of specialty malts: A review

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 20, Issue 5, Page 4816-4840, September 2021., 2021
Abstract Specialty malts comprise a promising field for innovative approaches concerning their potential in terms of color, aroma, and taste influence on the composition of beer and other beverages. Nevertheless, poor reproducibility of aroma and taste is a recurrent struggle between maltsters, leaving color as a practical parameter for quality control.

The anoxic electrode‐driven fructose catabolism of Pseudomonas putida KT2440

open access: yesMicrobial Biotechnology, Volume 14, Issue 4, Page 1784-1796, July 2021., 2021
A new pathway was uncovered for the fructose metabolism in Pseudomonas putida KT2440 cultivated anaerobically in a bioelectrochemical system. In addition to the typical PTS transporter‐based pathway observed under aerobic condition, fructose was firstly converted to mannose by isomerization and then oxidized to mannonate by the glucose dehydrogenase ...

Xylose isomerase from Piromyces:Characterization and engineering for improving S. cerevisiae-based lignocellulosic bioethanol production [PDF]

open access: yes, 2020
Lignocellulosic bioethanol has been recognized as a possible fossil fuel alternative. This so-called “second-generation” bioethanol has gained growing interest as it can be produced using agricultural waste material or side products in the food industry ...

Structure-based directed evolution improves S. cerevisiae growth on xylose by influencing in vivo enzyme performance [PDF]

open access: yes, 2020
Background: Efficient bioethanol production from hemicellulose feedstocks by Saccharomyces cerevisiae requires xylose utilization. Whereas S. cerevisiae does not metabolize xylose, engineered strains that express xylose isomerase can metabolize xylose by
