ApuA, a multifunctional x-glucan-degrading enzyme of Streptococcus suis, mediates adhesion to porcine epithelium and mucus [PDF]

, 2010
We have identified apuA in Streptococcus suis, which encodes a bifunctional amylopullulanase with conserved -amylase and pullulanase substrate-binding domains and catalytic motifs.

Pediatric Investigation Plans for seizure and epilepsy treatments: An analysis since the implementation of the European Pediatric Regulation in 2006

Epilepsia, EarlyView.
Abstract Objective A Pediatric Investigation Plan (PIP) implemented under the European Pediatric Regulation (EC No. 1901/2006) aims to ensure early and systematic evaluation of medicines for children. We analyze PIPs for antiseizure medications (ASMs) submitted to the European Medicines Agency (EMA) since 2006, characterizing their content, focusing on

The conserved XPF:ERCC1-like Zip2:Spo16 complex controls meiotic crossover formation through structure-specific DNA binding. [PDF]

, 2019
In eukaryotic meiosis, generation of haploid gametes depends on the formation of inter-homolog crossovers, which enable the pairing, physical linkage, and eventual segregation of homologs in the meiosis I division.

Intermittent transport of bacterial chromosomal loci [PDF]

, 2017
The short-time dynamics of bacterial chromosomal loci is a mixture of subdiffusive and active motion, in the form of rapid relocations with near-ballistic dynamics.

Structural analysis of the NifL‐NifA complex reveals the molecular basis of anti‐activation of nitrogen fixation gene expression in Azotobacter vinelandii

The FEBS Journal, EarlyView.
Using cryo‐EM combined with biochemical and genetic approaches, we mapped the interaction surface between NifL and NifA to gain insights into the regulation of nitrogen fixation genes in A. vinelandii. Our findings suggest that NifL, a homolog of histidine kinases lacking phosphorylation activity, evolved to act as a steric block of NifA activity ...

Epidemiology and Genetics of Rheumatic Diseases Suggest a Constant Rate of DNA Damage as Underlying Cause

Immunology, EarlyView.
A constant rate of DNA damage that is not perfectly repaired will cause a constant rate of DNA mutations. The chance of mutation will increase if DNA is prone to damage, such as occurs in somatic hypermutation (SHM) hotspots and GC‐rich DNA. Thus, if one mutation‐prone DNA site drives disease, the age of onset of disease and degree of penetrance should

Cell-Cycle Kinases Coordinate the Resolution of Recombination Intermediates with Chromosome Segregation

Cell Reports, 2013
Homologous recombination leads to the formation of DNA joint molecules (JMs) that must be resolved to allow chromosome segregation, but how resolution is temporally coupled with chromosome segregation is unknown.

Congenital microcephaly [PDF]

, 2014
The underlying etiologies of genetic congenital microcephaly are complex and multifactorial. Recently, with the exponential growth in the identification and characterization of novel genetic causes of congenital microcephaly, there has been a ...

A genetic algorithm simheuristic for solving the stochastic project portfolio selection problem with portfolio reliability constraints

International Transactions in Operational Research, EarlyView.
Abstract In response to the increasing complexity of modern products, dynamic markets, and intensified competition, project‐based organizations are actively seeking methodologies to efficiently manage their expanding project portfolios. This paper analyzes the project portfolio selection problem in uncertain environments. Despite recent advances in the

The MAP kinase pathway coordinates crossover designation with disassembly of synaptonemal complex proteins during meiosis

eLife, 2016
Asymmetric disassembly of the synaptonemal complex (SC) is crucial for proper meiotic chromosome segregation. However, the signaling mechanisms that directly regulate this process are poorly understood.
