Crystal structure of the plant GABA aminotransferase AtGABA-T from Arabidopsis thaliana. [PDF]
Acta Crystallogr F Struct Biol CommunThe crystal structure of A. thaliana γ‐aminobutyric acid aminotransferase (GABA‐T) reveals that plant GABA‐T belongs to the class III aminotransferase family and employs a C‐terminal arginine residue for γ‐aminobutyric acid recognition, in contrast to the N‐terminal arginine used by class II enzymes.γ‐Aminobutyric acid aminotransferase (GABA‐T) is a ...

Pyridoxal Phosphate-Responsive Epilepsy with Resistance to Pyridoxine
, 2009 We present a female infant with seizures responsive to pyridoxal phosphate but that are resistant to pyridoxine. The mechanism by which pyridoxal phosphate controls seizures in this patient is unknown.

Active site-directed inhibition of E. coli DNA-dependent RNA polymerase by pyridoxal 5′-phosphate
, 1973 peer reviewedDNA-dependent RNA polymerase from E. coli is rapidly inhibited by preincubation with pyridoxal 5′-phosphate. The enzyme is not inhibited by pyridoxamine 5′-phosphate or pyridoxine. Pyridoxal is about 10 times less effective than pyridoxal 5′-

Plant, Cell &Environment, EarlyView.ABSTRACT Bacteriophages impact soil bacteria through lysis, altering the availability of organic carbon and plant nutrients. However, the magnitude of nutrient uptake by plants from lysed bacteria remains unknown, partly because this process is challenging to investigate in the field.

Plants synthesize ergothioneine, showing a link to abiotic stress
Plant Biology, EarlyView.Various plants possess ergothioneine biosynthetic genes and can synthesize this antioxidant, where increased EGT levels under abiotic stress conditions indicate protective functions. Abstract Ergothioneine (EGT) is a sulphur‐containing histidine derivative and a potent antioxidant that exhibits beneficial effects on human health.

Altered Pharmacokinetics and Delayed Sputum Conversion in Tuberculosis Patients Co‐Infected With HIV
Tropical Medicine &International Health, EarlyView.ABSTRACT Background HIV co‐infection affects host responses and pharmacokinetics (PK) of tuberculosis (TB) treatment. This study assessed the PK of first‐line anti‐TB drugs and clinical outcomes in patients with and without HIV co‐infection. Methods In this prospective observational study, 61 adults with sputum‐positive pulmonary TB, either confirmed ...

An eye on long‐duration spaceflight: Controversies, countermeasures and challenges
Experimental Physiology, EarlyView.Abstract Space flight‐associated neuroocular syndrome (SANS) is a consequence of long‐duration space flight and is detected in two‐thirds of astronauts. In‐flight, this can cause a change in the refraction of the eyes, requiring graded hypermetropic ‘superfocus adjustable’ glasses, optic nerve head oedema and choroidal folds.
