Linear, diatomic crystal: single-electron states and large-radius excitons [PDF]

, 2008
The large-radius exciton spectrum in a linear crystal with two atoms in the unit cell was obtained using the single-electron eigenfunctions and the band structure, which were found by the zero-range potential (ZRP) method.

The anabolic steroid stanozolol is a potent inhibitor of human MutT homolog 1

FEBS Letters, EarlyView.
MutT homolog 1 (MTH1) is a member of the NUDIX superfamily of enzymes and is an anticancer drug target. We show that stanozolol (Stz), an anabolic steroid, is an unexpected nanomolar inhibitor of MTH1. The X‐ray crystal structure of the human MTH1–Stz complex reveals a unique binding scaffold that could be utilized for future inhibitor development ...

Carbon nitride quantum dots decorated with cyano groups for boosting photocatalytic hydrogen peroxide production

Green Energy & Environment
The photocatalytic hydrogen peroxide (H2O2) production by graphitic carbon nitride is a sustainable and environment-benign alternative approach of conventional anthraquinone autoxidation technology, but it is great challenges to promote two-electron O2 ...

Thermostable neutral metalloprotease from Geobacillus sp. EA1 does not share thermolysin's preference for substrates with leucine at the P1′ position

FEBS Letters, EarlyView.
Knowing how proteases recognise preferred substrates facilitates matching proteases to applications. The S1′ pocket of protease EA1 directs cleavage to the N‐terminal side of hydrophobic residues, particularly leucine. The S1′ pocket of thermolysin differs from EA's at only one position (leucine in place of phenylalanine), which decreases cleavage ...

Crystal structure of pymetrozine [PDF]

Acta Crystallographica Section E Crystallographic Communications, 2015
The title compound, C10H11N5O {systematic name: 6-methyl-4-[(E)-(pyridin-3-ylmethylidene)amino]-4,5-dihydro-1,2,4-triazin-3(2H)-one}, C10H11N5O, is used as an antifeedant in pest control. The asymmetric unit comprises two independent molecules,AandB, in which the dihedral angles between the pyridinyl and triazinyl ring planes [r.m.s.

Development of visible light‐sensitive human neuropsin (OPN5) via single amino acid substitution

FEBS Letters, EarlyView.
The present study determines a key amino acid residue, Lys91, for defining UV sensitivity of human OPN5. Heterologous action spectroscopy of the wild type and K91 mutants of OPN5 in HEK293T cells reveals that substitution of Lys91 with neutral (alanine) or acidic amino acids (glutamic or aspartic acids) causes substantial shifts in spectral sensitivity
