Structural and Biochemical Characterization of the Diaminopimelate Epimerase DapF From Pseudomonas aeruginosa PA14

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The emergence of antibiotic resistance in bacteria is a major threat to global public health. To combat increasingly drug‐resistant bacteria like Pseudomonas aeruginosa, new targets for pharmaceuticals need to be explored. One such potential target for P.

Genetic Tools in the Nakaseomyces clade for Evolutionary Comparisons of Signal Transduction Pathways

open access: yesYeast, EarlyView.
ABSTRACT The genus Nakaseomyces provides four species that are closely related but have different characteristics. For example, N. glabratus (formerly known as Candida glabrata) is a common human pathogen, whereas N. bracarensis and N. nivariensis have been isolated in clinical settings but are not common human pathogens. N.

Dystrophia Smolandiensis is characterized by a novel NQO1 variant and a distinct phenotype from COL17A1‐associated epithelial recurrent erosion dystrophy

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose To determine the molecular cause of the two epithelial recurrent erosion dystrophies, Dystrophia Smolandiensis and Dystrophia Helsinglandica, and to identify phenotypic differences between the two conditions. Methods DNA samples and clinical data from structured interview records were obtained from the Swedish families in which ...

Histopathologic Characterization of Cutaneous Oxalosis Mimicking Calciphylaxis: Diagnostic Pitfalls and Polarized Light Evaluation

open access: yesJournal of Cutaneous Pathology, EarlyView.
ABSTRACT Cutaneous oxalosis is an uncommon manifestation of primary hyperoxalosis, which can often resemble other cutaneous manifestations of end stage renal disease (ESRD), particularly calciphylaxis. We report the case of a 46 year old female with primary hyperoxaluria type one (PH1) believed to be well‐controlled on lumasiran, a small interfering ...

Prurigo Pigmentosa – an increasingly diagnosed dermatological condition associated with ketogenic diet

open access: yesJDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.
SUMMARY Prurigo pigmentosa (PP) is a rare inflammatory dermatosis, clinically characterized by intensely pruritic, erythematous papules and papulovesicles, with reticular hyperpigmentation upon healing. We herein report four cases in adults of different ethnic backgrounds, in which the disease was associated with ketogenic metabolic states due to ...

Comparative Study of Laboratory Diets for Piophila casei: Beneficial Effects of Infant Formula Supplementation

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
The infant formula‐based diet (F), the whole powder milk diet (P), and dry‐cured ham (H) were evaluated for rearing Piophila casei. H accelerated development, promoted earlier reproduction, and achieved the highest demographic performance but showed practical limitations linked to substrate deterioration. F enhanced larval survival and adult longevity,

Enantioselective Formation of Amino Acids by Isomerization of Mixed Ligand Copper(ll) Schiff-Base Complexes

open access: yesCHIMIA, 1993
The formation of optically active phenylalanine from phenylpyruvic acid and pyridoxamine in the presence of various chiral CuII complexes was investigated as a function of the reaction conditions.

A new branch of mammalian vitamin B6 metabolism: AKR1C‐mediated conversion of pyridoxal to pyridoxine and 4‐pyridoxolactone

open access: yesThe FEBS Journal, EarlyView.
Pyridoxal 5′‐phosphate (PLP) homeostasis relies on salvage enzymes, yet key metabolic branches remain undefined. We identify AKR1C isozymes as previously undescribed contributors that convert pyridoxal into pyridoxine or 4‐pyridoxolactone through reductase and dehydrogenase activities.

A distinct gene expression mechanism for d‐amino acid utilization in hyperthermophilic archaeon Pyrococcus horikoshii

open access: yesThe FEBS Journal, EarlyView.
The genes PH0137, PH0138, and PH0140 form a cluster in the genome of Pyrococcus horikoshii. The PH0140 gene encodes a transcription factor identified as a d‐amino acid‐responsive regulatory protein (DARP). In feast mode, l‐Ile‐bound DARP binds to the promoter and represses transcription of PH0137 and PH0138. In famine mode, DARP binds to d‐allo‐Ile and

Prebiotic aqueous reactions catalyzed by native nickel without hydrogen

open access: yesThe FEBS Journal, EarlyView.
Serpentinizing (H2‐producing) hydrothermal vents are candidate environments for metabolic origin. They generate highly reducing conditions that convert CO2 to formate and methane in abiotic reactions resembling reactions of the acetyl‐CoA pathway of CO2 fixation. They also contain natural catalysts. Native nickel (Ni0), like Fe0, Co0, and their alloys,
