A Stable Bioisostere of Ester-Linked Ubiquitin Chains Enables Decoding of Protein Interactors. [PDF]

open access: yesChembiochem
An ester‐to‐amide analog of an ester‐linked ubiquitin dimer is chemically synthesized through a convergent approach involving the sequential chemoselective ligation of three peptide fragments generated through Fmoc‐based solid‐phase peptide synthesis. The hydrolysis‐resistant ubiquitin dimer served as a chemical probe in the identification of potential

The Curious Case of CysE: Diversity and Distribution of Serine Acetyltransferases in Bacteria

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Serine acetyltransferase (CysE) is a member of the left‐handed β‐helix family of acetyltransferases that catalyze the rate limiting step in de novo cysteine biosynthesis. There are two isoforms of CysE that differ in length, with the shorter isoform lacking approximately 76 amino acids at the N‐terminus of the protein from the serine ...

Status Transfer across Borders: The Mediating Role of Common Partners in First Entry

open access: yesJournal of Management Studies, EarlyView.
Abstract Recent studies on organizational status and international business (IB) have found evidence for the transferability of status to new markets by showing that, at least under certain circumstances, network status in the home market affects a firm's entry into and performance in new foreign markets; however, the status transfer mechanisms in ...

Institutional Logics as a Resource and Risk: Logic Deviance and Categorical Penalties in US Community Banks

open access: yesJournal of Management Studies, EarlyView.
Abstract Can institutional logics be damaging for the same category of actors they are presumed to benefit? Can firms prevent or reduce this detrimental effect? This study integrates the institutional logics perspective with category research to examine these questions in the context of community banks.
