Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Map of fossil resins of Ukraine

open access: yesМінеральні ресурси України, 2020
Finding out the conditions of the geological past under which tar secretions were fossilised and primary bio-sedimentary deposits of protoamber were accumulated and amber-succinite placers formed in the marine environment is an important link in ...

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

open access: yesFEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

INTERGROWTHS OF PLATINUM GROUP MINERALS FROM THE MIASS PLACER ZONE (SOUTH URALS) AND THEIR PRIMARY SOURCES [PDF]

open access: yesМинералогия, 2016
Twenty four platinum group minerals (PGMs) were found in the Kialim and Maly Iremel gold placers of the Miass placer zone, South Urals. Rhodarsenite, bowieite, cuprorhodiste, and xingzhongite(?) were found in the Urals for the first time.
