Human IDO2 exhibits unique binding affinities distinct to those of human IDO1

open access: yesThe FEBS Journal, EarlyView.
Although indoleamine 2,3‐dioxygenase 2 (IDO2) is highly homologous to IDO1, it displays markedly lower catalytic activity. We found that IDO2 binds L‐tryptophan (L‐Trp) in a flipped orientation stabilized by the IDO2‐specific residue His143. Replacement of His143 with the IDO1‐equivalent tyrosine restored an IDO1‐like binding mode and increased ...

Review of lightning protection standard in building structures in Nigeria. [PDF]

open access: yes, 2014
A lightning protection system performs a simple task. It provides a specified path on which lightning can travel. When a building structure is equiped with a lightning protection system, the distructive power of the lightning strike is directed safely ...

Unraveling the active site cover of coproheme decarboxylase from Listeria monocytogenes

open access: yesThe FEBS Journal, EarlyView.
During heme biosynthesis in Gram‐positive bacteria, coproheme decarboxylase (ChdC) catalyzes the conversion of four‐propionate substrate coproheme to the two propionate product heme b. Its active site is universally covered by a flexible linking loop. This study identifies an important histidine residue, which stabilizes the loop in a ChdC homolog.

Two Faces of the Anti‐Inclusion Neoconservative Coin in Brazil: Neoliberalism and Far‐Right

open access: yesGender, Work &Organization, EarlyView.
ABSTRACT Brazil has recently experienced the resurgence of the far‐right, a movement that has also occurred in other countries around the world. Given this context, this article seeks to understand the factors that enabled the union among neoliberalism, neoconservatism, and the far‐right in Brazil, demonstrating that in times of economic crisis the ...

Quality Regulation and Unexpected Gaming: Evidence From Mandating Flight Delay Compensation

open access: yesJournal of Economics &Management Strategy, EarlyView.
ABSTRACT Policies that target a single aspect of agents' motivation may lead to their diminished efforts in other areas. This paper examines the effect of the European Union's flight delay compensation policy on flight on‐time performance by exploiting a unique policy variation in a difference‐in‐differences framework.

Thunderstorm total lightning activity behavior associated with transmission line trip events of power system

open access: yesnpj Climate and Atmospheric Science
High-voltage transmission lines are susceptible targets for lightning strikes. It is an interesting topic how the trip event of transmission line is related to the area, location, and intensity of thunderstorms occurring at that time and that place ...

Natural disaster risk salience and the strategic appointment of directors with sustainability expertise

open access: yesJournal of Financial Research, EarlyView.
Abstract This article examines how salient sustainability risks from near‐miss natural disasters influence board composition. Using a difference‐in‐differences design, I find that firms located in counties neighboring disaster‐affected areas significantly increase the presence of directors with sustainability expertise following the disaster.
