A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Exploring Important Protein Interactions in the Mammalian Diaphanous-related Formins: A Closer Look at the Relationship between the Intracellular Skeletal Network and a Single Amino Acid Residue [PDF]

open access: yes, 2006
The Diaphanous-related formin protein family plays a key role in intracellular cytoskeletal regulation. Due to their farreaching importance, these proteins must be highly regulated themselves.

The ubiquitin ligase RNF115 is required for the clearance of damaged lysosomes

open access: yesFEBS Letters, EarlyView.
Upon lysosomal rupture, an E3 ubiquitin ligase RNF115 translocates from the cytosol to the damaged lysosomal membrane. Moreover, RNF115 depletion impairs the clearance of damaged lysosomes, identifying it as a key regulator of lysosomal quality control.

Involvement of BcYak1 in the Regulation of Vegetative Differentiation and Adaptation to Oxidative Stress of Botrytis cinerea

open access: yesFrontiers in Microbiology, 2018
Yak1, a member of the dual-specificity tyrosine phosphorylation-regulated protein kinases, plays an important role in diverse cellular processes in fungi. However, to date, the role of BcYak1 in Botrytis cinerea, the causal agent of gray mold diseases in

Functional studies on oligotropha carboxidovorans molybdenum–copper CO dehydrogenase produced in escherichia coli [PDF]

open access: yes, 2018
The Mo/Cu-dependent CO dehydrogenase (CODH) from Oligotropha carboxidovorans is an enzyme that is able to catalyze both the oxidation of CO to CO2 and the oxidation of H2 to protons and electrons. Despite the close to atomic resolution structure (1.1 Å),

AAA+ protein unfoldases—the Moirai of the proteome

open access: yesFEBS Letters, EarlyView.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

Identification of amino acid residues in the ligand binding repeats of LDL receptor important for PCSK9 binding[S]

open access: yesJournal of Lipid Research, 2019
Proprotein convertase subtilisin/kexin type 9 (PCSK9) promotes LDL receptor (LDLR) degradation, increasing plasma levels of LDL cholesterol and the risk of cardiovascular disease.

Site directed mutagenesis and purification of the cDNA for human class I aldehyde dehydrogenase : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science at Massey University [PDF]

open access: yes, 1998
Aldehyde dehydrogenase (ALDH) is a key enzyme of alcohol metabolism, removing acetaldehyde which is formed as a product of the alcohol dehydrogenase reaction.

Cytolytic T lymphocyte recognition of the murine cytomegalovirus nonstructural immediate-early protein pp89 expressed by recombinant vaccinia virus [PDF]

open access: yes, 1987
The murine immediate-early (IE) protein pp89 is a nonstructural virus- encoded phosphoprotein residing in the nucleus of infected cells, where it acts as transcriptional activator.
