Mechanism of cyanobacterial ferredoxin‐dependent flavin thioredoxin reductase reveals thiolate‐FAD charge transfer and catalytic asymmetry in a homodimer

open access: yesThe FEBS Journal, EarlyView.
Ferredoxin‐dependent flavin thioredoxin reductases (FFTRs) regenerate reduced thioredoxin, sustaining dithiol–disulfide exchange reactions that regulate protein activity in select organisms. In cyanobacterial FFTRs, we describe the formation of a thiolate–flavin charge transfer complex, asynchronous reduction of the two FAD cofactors within the ...

A novel single‐cell NAD‐ME C4 subtype integrated with CAM and bicarbonate use in an aquatic plant

open access: yesNew Phytologist, EarlyView.
Summary Many plants maximize photosynthesis by using a CO2‐concentrating mechanism (CCM). Based on physiology, the freshwater plant Ottelia alismoides has three CCMs: C4 metabolism (NAD‐malic enzyme (NAD‐ME) subtype) and bicarbonate‐use during the day plus crassulacean acid metabolism (CAM) at night and lacks Kranz anatomy. Here, we combined a range of

Shortcutting photorespiration: avenues and challenges toward realizing higher‐yielding photorespiratory bypass crops

open access: yesNew Phytologist, EarlyView.
Summary Photorespiration is a major source of photosynthetic inefficiency in C3 crops. In photorespiration, the oxygenation rather than carboxylation of RuBP by Rubisco triggers an energy‐expensive pathway to recycle inhibitory byproducts and recapture lost carbon, ultimately reducing yields.

U.S. Geological Survey External Quality-Assurance Project Report for the National Atmospheric Deposition Program / National Trends Network and Mercury Deposition Network, 2011-12 [PDF]

open access: yes, 2014
The U.S. Geological Survey operated six distinct programs to provide external quality-assurance monitoring for the National Atmospheric Deposition Program (NADP) / National Trends Network (NTN) and Mercury Deposition Network (MDN) during 2011–2012.

Microbiome and Metaproteome of Craniofacial Implant Regions in Health and Disease

open access: yesOral Diseases, EarlyView.
ABSTRACT Background Craniofacial defects from cancer surgery led to functional, aesthetic, and psychological challenges. Rehabilitation with craniofacial implants addresses these issues by improving prosthesis retention through osseointegration and providing predictable cosmetic results. However, maintaining a healthy transcutaneous region is essential
