Proteins: Structure, Function, and Bioinformatics, EarlyView.ABSTRACT BorF is a short‐chain flavin reductase from a desert soil bacterium that uses NADH to reduce FAD to FADH2, which is used by the tryptophan‐6‐halogenase BorH to chlorinate tryptophan in the biosynthetic pathway of borregomycin A. The X‐ray crystal structure of BorF bound to FAD was solved to 2.37 Å by molecular replacement.

Pest Management Science, EarlyView.Alcoholic extracts from flowers, leaves, and shoots of Russian sage decreased downy mildew severity on grapevine leaf disks. Fractionation followed by metabolomic analysis revealed putative terpenoids as the main components of the active fractions. Specifically, 7‐methylrosmanol, 12‐O‐methylcarnosic acid, carnosic acid, and carnosol were identified as ...

Initiation of Olefin Metathesis: Reaction of Deca-2,8-diene with Catalysts formed from Me_4Sn-WC1_6 and Me_3Al_2Cl_3-(Ph_3P)_2(NO)_2Cl_2Mo [PDF]
, 1977 The initial product of the metathesis of deca-2,8-diene with metathesis catalysts formed from either Me_4Sn–WCl_6 or Me_3Al_2Cl_3–(Ph_3P)_2(NO)_2Cl_2Mo is propene; labelling of the terminal groups of the diene and the alkylating agents gives a labelling ...

Small, EarlyView.Atomically dispersed Cu sites on Co3O4 nanoparticles establish well‐defined Cu–O–Co interfacial linkages that promote lattice oxygen activation at markedly reduced temperatures. This structural and electronic modulation yields over twenty‐fold higher low‐temperature formaldehyde sensing responses than CuO nanoparticle analogues, enabling selective and ...

Environmental Toxicology, EarlyView.ABSTRACT Mancozeb is one of the most widely used agricultural fungicides, exhibiting strong efficacy against a broad spectrum of phytopathogenic fungi. However, its widespread application comes at the cost of environmental contamination. Here, we show the effects of Inga vera leaf litter contamination with Mancozeb on life‐history traits of Aedes ...

Modeling Soil-Facing Interface Interaction With Continuum Element Methodology
Frontiers in Built Environment, 2022 Soil-facing mechanical interactions play an important role in the behavior of earth-retaining walls. Generally, numerical analysis of earth-retaining structures requires the use of interface elements between dissimilar component materials to model soil ...

Deca-Arylsamarocene: An Unusually Inert Sm(II) Sandwich Complex [PDF]
Organometallics, 2018 Samarocene sandwich complexes with superbulky penta-arylcyclopentadienyl ligands have been prepared and were structurally characterized: [(4-EtC6H4)(5)C-5](2)Sm (1) and [(4-iPrC(6)H(4))(5)C-5](2)Sm (2). Analogous to the previously reported synthesis of [(4-nBuC(6)H(4))(5)C-5](2)Sm, reaction of (DMAT)(2)center dot Sm(THF)(2) (DMAT = 2-Me2N-alpha-Me3Si ...

Evidence About Discipline Committees and Professional Misconduct of Auditors*,‡
Accounting Perspectives, EarlyView.ABSTRACT Self‐regulating professions establish professional discipline processes to determine whether members' behavior falls short of expectations outlined in their respective codes of conduct and to determine appropriate sanctions when necessary. From an auditing perspective, audit quality is of primary interest to audit researchers, yet few prior ...
