The deep-subsurface sulfate reducer Desulfotomaculum kuznetsovii employs two methanol-degrading pathways [PDF]

open access: yes, 2018
Methanol is generally metabolized through a pathway initiated by a cobalamine-containing methanol methyltransferase by anaerobic methylotrophs (such as methanogens and acetogens), or through oxidation to formaldehyde using a methanol dehydrogenase by ...

Nephrotoxicity of pyrroloquinoline quinone in rats.

open access: yesHiroshima journal of medical sciences, 1989
When pyrroloquinoline quinone (PQQ) was intraperitoneally injected into rats daily for 4 days at a dose of 11.5 mg/kg body weight/injection, functional and morphologic changes of the kidneys were clearly observed. The most prominent finding was necrotic and degenerative changes of the proximal tubular epithelium as well as hematuria and an elevation of

The fox Operon from Rhodobacter Strain SW2 Promotes Phototrophic Fe(II) Oxidation in Rhodobacter capsulatus SB1003 [PDF]

open access: yes, 2007
Anoxygenic photosynthesis based on Fe(II) is thought to be one of the most ancient forms of metabolism and is hypothesized to represent a transition step in the evolution of oxygenic photosynthesis.

Pyrroloquinoline Quinone: Tissue Distribution and Metabolism

open access: yesThe FASEB Journal, 2008
Pyrroloquinoline quinone (PQQ) acts as a growth factor affecting a variety of systemic functions when deficient in diets (e.g. reduced mitochondria, altered lipid metabolism). Moreover, PQQ is hypothesized as important in the modulation of reactive oxygen species (ROS).

Role of methylotrophy during symbiosis between Methylobacterium nodulans and Crotalaria podocarpa [PDF]

open access: yes, 2005
Some rare leguminous plants of the genus Crotalaria are specifically nodulated by the methylotrophic bacterium Methylobacterium nodulans. In this study, the expression and role of bacterial methylotrophy were investigated during symbiosis between M ...

The Effect of Pyrroloquinoline Quinone on the Expression of WISP1 in Traumatic Brain Injury

open access: yesStem Cells International, 2017
WISP1, as a member of the CCN4 protein family, has cell protective effects of promoting cell proliferation and inhibiting cell apoptosis. Although some studies have confirmed that WISP1 is concerned with colon cancer and lung cancer, there is little ...

Aspects of the Release of Superoxide by Leukocytes, and a Means by Which This Is Switched Off [PDF]

open access: yes, 2010
Although great progress has been made in understanding the respiratory burst of leukocytes that produce superoxide (O2-), it is possible that a component or components, might have been overlooked.
