Hyperaccumulation of Gadolinium by Methylorubrum extorquens AM1 Reveals Impacts of Lanthanides on Cellular Processes Beyond Methylotrophy

open access: yesFrontiers in Microbiology, 2022
Lanthanides (Ln) are a new group of life metals, and many questions remain regarding how they are acquired and used in biology. Methylotrophic bacteria can acquire, transport, biomineralize, and use Ln as part of a cofactor complex with pyrroloquinoline ...

SPASM and Twitch Domains in S-Adenosylmethionine (SAM) Radical Enzymes [PDF]

open access: yes, 2014
S-Adenosylmethionine (SAM, also known as AdoMet) radical enzymes use SAM and a [4Fe-4S] cluster to catalyze a diverse array of reactions. They adopt a partial triose-phosphate isomerase (TIM) barrel fold with N- and C-terminal extensions that tailor the ...

Characterization of a novel PQQ-dependent quinohemoprotein pyranose dehydrogenase from Coprinopsis cinerea classified into auxiliary activities family 12 in carbohydrate-active enzymes. [PDF]

open access: yesPLoS ONE, 2015
The basidiomycete Coprinopsis cinerea contains a quinohemoprotein (CcPDH named as CcSDH in our previous paper), which is a new type of pyrroloquinoline-quinone (PQQ)-dependent pyranose dehydrogenase and is the first found among all eukaryotes.

Characterisation of the PQQ cofactor radical in quinoprotein ethanol dehydrogenase of Pseudomonas aeruginosa by electron paramagnetic resonance spectroscopy [PDF]

open access: yesFEBS Letters, 2004
The binding pocket of the pyrroloquinoline quinone (PQQ) cofactor in quinoprotein alcohol dehydrogenases contains a characteristic disulphide ring formed by two adjacent cysteine residues. To analyse the function of this unusual structural motif we have investigated the wild‐type and a double cysteine:alanine mutant of the quinoprotein ethanol ...

Identification and Biochemical Characterization of a PQQ-dependent Deoxynivalenol (DON) Dehydrogenase

open access: yesLiang you shipin ke-ji, 2023
Deoxynivalenol (DON) contamination in cereals and cereal products has the potential to pose a threat to human health. The biodetoxification technique, which uses biological enzymes to transform mycotoxins into less toxic product, is an environmentally ...

Engineering thermal stability and solvent tolerance of the soluble quinoprotein PedE from Pseudomonas putida KT2440 with a heterologous whole-cell screening approach [PDF]

open access: yes, 2018
Due to their ability for direct electron transfer to electrodes, the utilization of rare earth metals as cofactor, and their periplasmic localization, pyrroloquinoline quinone‐dependent alcohol dehydrogenases (PQQ‐ADHs) represent an interesting class of ...
