Microbial keystone taxa drive succession of plant residue chemistry [PDF]

open access: yesISME Journal, 2023
Abstract Managing above-ground plant carbon inputs can pave the way toward carbon neutrality and mitigating climate change. Chemical complexity of plant residues largely controls carbon sequestration. There exist conflicting opinions on whether residue chemistry diverges or converges after long-term decomposition.

Infrared Techniques Useful in Residue Chemistry

open access: yesJournal of AOAC INTERNATIONAL, 1965
Abstract Although infrared spectrophotometry is suitable for the measurement and identification of pesticides and their metabolic products because of its inherent characterizing properties, only recently have techniques and instrumentation become adequate for the difficult requirements of residue chemistry.

In silico prediction of mutant HIV-1 proteases cleaving a target sequence [PDF]

open access: yes, 2014
HIV-1 protease represents an appealing system for directed enzyme re-design, since it has various different endogenous targets, a relatively simple structure and it is well studied.

Controlling tetramer formation, subunit rotation and DNA ligation during Hin-catalyzed DNA inversion. [PDF]

open access: yes, 2015
Two critical steps controlling serine recombinase activity are the remodeling of dimers into the chemically active synaptic tetramer and the regulation of subunit rotation during DNA exchange.

pH-dependent mechanism of nitric oxide release in nitrophorins 2 and 4 [PDF]

open access: yes, 2009
Nitrophorins are NO carrier proteins that transport and release NO through a pH-dependent conformational change. They bind NO tightly in a low pH environment and release it in a higher pH environment.

Applications of Direct Injection Soft Chemical Ionisation-Mass Spectrometry for the Detection of Pre-blast Smokeless Powder Organic Additives [PDF]

open access: yes, 2019
Analysis of smokeless powders is of interest from forensics and security perspectives. This article reports the detection of smokeless powder organic additives (in their pre-detonation condition), namely the stabiliser diphenylamine and its derivatives 2-
