Autotrophic carbon fixation pathways along the redox gradient in oxygen‐depleted oceanic waters

open access: yesEnvironmental Microbiology Reports, 2020
Summary Anoxic marine zones (AMZs), also known as ‘oxygen‐deficient zones’, contribute to the loss of fixed nitrogen from the ocean by anaerobic microbial processes. While these microbial processes associated with the nitrogen cycle have been extensively

Carbon dioxide fixation in trypanosomatids

open access: yesParasitology, 1975
Fixation of carbon dioxide has been demonstrated for extracts fromCrithidia fasciculata, Trypanosoma megaandTrypanosoma brucei bruceibloodstream and culture forms. The enzymes involved in this fixation were found to be ADP-stimulated phosphoenolpyruvate carboxykinase (E.C. 4. 1. 1. 32), ‘malic’ enzyme (E.C. 1. 1. 138–40) and pyruvate carboxylase (E. 0.

Molecular bases of circadian magnesium rhythms across eukaryotes

open access: yesFEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Efficient conversion of hemicellulose into high-value product and electric power by enzyme-engineered bacterial consortia

open access: yesNature Communications
As an abundant agricultural and forestry biomass resource, hemicelluloses are hard to be effectively degraded and utilized by microorganisms due to the constraints of membrane and metabolic regulations.

Diurnal variation in the coupling of photosynthetic electron transport and carbon fixation in iron-limited phytoplankton in the NE subarctic Pacific [PDF]

open access: yesBiogeosciences, 2016
Active chlorophyll a fluorescence approaches, including fast repetition rate fluorometry (FRRF), have the potential to provide estimates of phytoplankton primary productivity at an unprecedented spatial and temporal resolution.

The compositional and evolutionary logic of metabolism

open access: yes, 2012
Metabolism displays striking and robust regularities in the forms of modularity and hierarchy, whose composition may be compactly described. This renders metabolic architecture comprehensible as a system, and suggests the order in which layers of that ...

The Outer Tracker Detector of the HERA-B Experiment Part I: Detector [PDF]

open access: yes, 2005
The HERA-B Outer Tracker is a large system of planar drift chambers with about 113000 read-out channels. Its inner part has been designed to be exposed to a particle flux of up to 2.10^5 cm^-2 s^-1, thus coping with conditions similar to those expected ...

CDK11 inhibition induces cytoplasmic p21WAF1 splice variant by p53 stabilisation and SF3B1 inactivation

open access: yesMolecular Oncology, EarlyView.
CDK11 inhibition stabilises the tumour suppressor p53 and triggers the production of an alternative p21WAF1 splice variant p21L, through the inactivation of the spliceosomal protein SF3B1. Unlike the canonical p21WAF1 protein, p21L is localised in the cytoplasm and has reduced cell cycle‐blocking activity.

When green carbon plants meet synthetic biology

open access: yesModern Agriculture, 2023
Recycling carbon dioxide (CO2) into chemicals or fuels presents a promising avenue for mitigating carbon emissions and addressing the energy crisis. Plants serve as the ideal platform for the production of materials and chemicals, thanks to their innate ...

Solar-driven carbon dioxide fixation using photosynthetic semiconductor bio-hybrids. [PDF]

open access: yes, 2019
Solar-driven conversion of carbon dioxide to value-added carbon products is an ambitious objective of ongoing research efforts. However, high overpotential, low selectivity and poor CO2 mass transfer plague purely inorganic electrocatalysts.
