Could tyrosine and tryptophan serve multiple roles in biological redox processes?

Could tyrosine and tryptophan serve multiple roles in biological redox processes?

Single-step electron tunnelling reactions can transport charges over distances of 15-20 Åin proteins. Longer-range transfer requires multi-step tunnelling processes along redox chains, often referred to as hopping. Long-range hopping via oxidized radicals of tryptophan and tyrosine, which has been identified in several natural enzymes, has been demonstrated in artificial constructs of the blue ...

performance of biological system and advanced oxidation processes (aop) treating antibiotic production industrial wastewater

در این مطالعه، عملکرد دو سیستم اکسیداسیون شیمیایی پیشرفته و یک سیستم بیولوژیکی برای حذف آموکسی سیلین در فاضلاب های سنتزیدر غلظت های مشابه با موارد صنعتی مورد بررسی قرار گرفته شدند. مطالعه انجام شده دارای سه بخش متفاوت اکسیداسیون با ازن و اشعه uv، اکسیداسیون با استفاده از نانو فتوکاتالیست tio2 و استفاده از بیوراکتور هوازی لجن فعال با جداکننده های فیزیکی می باشد. در هر بخش، متغیر های متفاوتی متنا...

Multiple Representations of Biological Processes

This paper describes representations of biological processes based on Rewriting Logic and Petri net formalisms and mappings between these representations used in the Pathway Logic Assistant. The mappings are shown to preserve properties of interest. In addition a relevant subnet transformation is defined, that specializes a Petri net model to a specific query to reduce the number of transitions...

Mediating Tyrosine and Tryptophan Uptake

Biological roles of vascular endothelial cell in various pathologic processes.

As Thorgeirsson and Kawanami reported, vascular endothelium has very important roles in the pathogenesis of various diseases, including atherosclerosis and lung disease. Endothelial cells play important roles in physiological responses, and the endothelial layer in most areas may play a role as a barrier which regulates transfer of varied molecular size substances between the circulating blood ...
