The mathematical modeling and description of complex biological processes has become more and more important over the last years. Systems biology aims at the computational simulation of complex systems, up to whole cell simulations. An essential part focuses on solving a large number of parameterized differential equations. However, measuring those parameters is an expensive task, and finding t...
The mechanism of protein-only prion replication is controversial. A detailed mathematical model of prion replication by nucleated polymerisation is developed, and its parameters are estimated from published data. PrP-res decay is around two orders of magnitude slower than PrP-sen decay, a plausible ratio of two parameters estimated from very different experiments. By varying the polymer breakag...
Protein thermostability engineering is a powerful tool to improve resistance of proteins against high temperatures and thereafter broaden their applications. For efficient protein thermostability engineering, different thermostability-classified data sources including sequences and 3D structures are needed for different protein families. However, no data source is available providing such data ...
Determinations of lifetime for propellants require exact evaluation of thermal decomposition kinetic parameters. Thermal analysis is one of the tools for investigation of thermal decomposition reaction and its kinetic parameters. In this article, thermal decomposition process for a single-base propellant is investigated under 1, 2 and 3 K/min heating rates. Then by using Friedman isoconversiona...
The thermostability of Streptomyces lividans xylanase B (SlxB-cat) was significantly increased by the replacement of its N-terminal region with the corresponding region from Thermomonospora fusca xylanase A (TfxA-cat) without observing a decrease in enzyme activity. In spite of the significant similarity between the amino acid sequences of the two xylanases, their thermostabilities are quite di...
in present study, the kinetic parameters of purified trypsin from pyloric caeca of common kilka (c.cultriventris caspia) were measured using the amidolytic (bapna) and esterolytic (tame) substrates. the results of the kinetic comparison between bapna and tame substrates showed that kinetic parameters including maximum velocity (vmax), catalytic constant (kcat) and catalytic efficiency (kcat/km)...
The kinetic analysis of complex solid-state reactions that involve simultaneous overlapping processes is challenging. A method that involves the deconvolution of the individual processes from the overall differential kinetic curves obtained under linear heating rate conditions, followed by the kinetic analysis of the discrete processes using combined kinetic analysis, is proposed. Different con...
