Quantification of Chitinase Activity in Fusarium oxysporum Authors:  Carmen Ruiz-Roldan and M. Isabel G. Roncero, date: 08/05/2016, view: 11990, Q&A: 1
Fungal morphogenetic development requires modification and plasticity of the cell wall, which implies synthesis and remodelling of its components, including chitin and glucan. Thus chitinase and glucanase activities are crucial for cell-wall biogenesis and cell division. Quantification of chitinase activity might be useful to identify structural ...

Analytical Gel Filtration for Probing Heavy Metal Transfer between Proteins Authors:  Steffen Lorenz Drees and Mathias Lübben, date: 08/05/2016, view: 9551, Q&A: 0
Heavy metals can cause damage to biomolecules such as proteins and DNA in multiple ways. Cells therefore strive for keeping intracellular (heavy) metal ions bound to specific proteins that are capable of handling detoxification, export or integration as cofactors. Metal binding proteins usually provide specific coordination sites that bind certain ...

A Live-imaging, Heat Shock-inducible System to Measure Aux/IAA Degradation Rates in Planta Authors:  Jessica M. Guseman, Jennifer L. Nemhauser and Britney L. Moss, date: 08/05/2016, view: 9418, Q&A: 0
An emerging theme in biology is the importance of cellular signaling dynamics. In addition to monitoring changes in absolute abundance of signaling molecules, many signal transduction pathways are sensitive to changes in temporal properties of signaling components (Purvis and Lahav, 2013). The phytohormone auxin regulates myriad processes in plant ...

Mouse Liver Mitochondria Isolation, Size Fractionation, and Real-time MOMP Measurement Authors:  Thibaud T. Renault, Mark P.A Luna-Vargas and Jerry E. Chipuk, date: 08/05/2016, view: 10914, Q&A: 0
The mitochondrial pathway of apoptosis involves a complex interplay between dozens of proteins and lipids, and is also dependent on the shape and size of mitochondria. The use of cellular models in past studies has not been ideal for investigating how the complex multi-factor interplay regulates the molecular mechanisms of mitochondrial outer ...

In vivo DCs Depletion with Diphtheria Toxin and MARCO+/MOMA1+ Cells Depletion with Clodronate Liposomes in B6.CD11c-DTR Mice Authors:  Henrique Borges da Silva, Carlos Eduardo Tadokoro and Maria Regina D’Império Lima, date: 08/05/2016, view: 9669, Q&A: 0
To evaluate precisely the relative roles of different splenic phagocytic cells during an immune response, efficient methods for the depletion of specific populations are needed. Here, we describe the protocols for the depletion of splenic dendritic cells (DCs) by human diphtheria toxin (DTx) treatment in target mice (which express the human DTx ...

A Highly Efficient Method for Measuring Oxygen Consumption Rate in Fusarium graminearum Authors:  Daniel Gebhard, Jakob Bönnighausen, Jörg Bergemann, Wilhelm Schäfer and Jörg Bormann, date: 08/05/2016, view: 9186, Q&A: 0
The filamentous ascomycete Fusarium graminearum is the causal agent of Fusarium head blight, a devastating disease of cereals with a worldwide distribution. Fusarium graminearum infections result in a quantitative yield reduction by impairing the growth of the kernels, and a qualitative reduction by poisoning the ...

Antifungal and Zearalenone Inhibitory Activity of Ocimum sanctum L. Essential Oil on Fusarium graminearum Determined by UHPLC and RT-qPCR Authors:  Naveen Kumar Kalagatur, Nirmaladevi Dhamodaran, Chandranayaka Siddaiah, Venkataramana Mudili and Murali Harishchandra Sreepathi, date: 08/05/2016, view: 8517, Q&A: 0
Fusarium graminearum has been given special attention in the context of agricultural commodities due to its ability to grow in diverse climatic conditions, and to produce different mycotoxins including zearalenone (ZEA) and type-B trichothecenes, which cause ill health effects on humans, animals and plants. The application of synthetic ...

Generation of IgG-Fc Glycovariants Using Recombinant Glycosidases and Glycosyltransferases Authors:  Isaak Quast, Michael A. Maurer and Jan D. Lünemann, date: 08/05/2016, view: 11314, Q&A: 0
The immunoglobulin G (IgG) fragment crystallizable (Fc) domain contains a single, highly conserved asparagine 297 (N297) glycosylation site in the CH2 domain, which is buried within the hydrophobic core of each of the two heavy chains. The biantennary core glycan structure, composed of 2 N-acetylglucosamine (GlcNAc) and 3 mannose residues, can be ...

Target Gene Inactivation in Cyanobacterium Anabaena sp. PCC 7120 Authors:  Kangming Chen, Huilan Zhu, Liping Gu, Shengni Tian and Ruanbao Zhou, date: 08/05/2016, view: 9330, Q&A: 0
Anabaena sp. strain PCC 7120 has long served as a model organism for investigating N2-fixation, photosynthesis, and various plant-type metabolic pathways and biofuel production, as well as cellular differentiation (Xu et al., 2008, Halfmann et al., 2014, Golden and Yoon, 2003). Since more than 30,000 sequenced ...
