Описание:
With usage of mass spectrometry continually expanding, an increasing number of scientists, technicians, students, and physicians are coming into contact with this valuable technique. Mass spectrometry has many uses, both qualitative and quantitative, from analyzing simple gases to environmental contaminants, pharmaceuticals, and complex biopolymers. The extraordinary versatility can make mass spectrometers daunting to novices. Consequently, new users would benefit greatly from an understanding of the basic concepts as well as the processes that occur in these instruments. Mass Spectrometry for the Novice provides exactly that, with detailed, straightforward descriptions and clear illustrations of principles of operations and techniques.
The book begins with an overview that includes essential definitions and then provides information on the components of and the strategies used in the most common instruments. The authors discuss the methodologies available, classes of compounds analyzed, and the types of data that can be generated. A group of representative applications from published articles is summarized, demonstrating the diversity of mass spectrometry. The authors also condense the essentials of the topic into one invaluable chapter that provides a set of concise take-home messages on all aspects of mass spectrometry. The final section provides a collection of resources including books, reviews, and useful websites. Using simple language, new color figures, clever cartoons, and assuming no prior knowledge, this book provides a readily understandable entr e to mass spectrometry. A CD-ROM with selected figures and cartoons is included.
Описание: This thesis reports studies on the substrate specificity of crucial ketosynthase (KS) domains from trans-AT Polyketide Synthases (PKSs). Using a combination of electrospray ionisation-mass spectrometry (ESI-MS) and simple N-acetyl cysteamine (SNAC) substrate mimics, the specificity of a range of KS domains from the bacillaene and psymberin PKSs have been succsessfully studied with regard to the initial acylation step of KS-catalysis. In addition, the ability to alter the substrate tolerance of KS domains by simple point mutations in the active site has been demonstrated. A series of acyl-ACPs have been synthesised using a novel methodology and employed to probe the substrate specificity of both KS domains and the previously uncharcterised acyl hydrolase domain, PedC. KS-catalysed chain elongation reactions have also been conducted and monitored by ESI-MS/MS. All KS domains studied exhibited higher substrate specificity at the elongation step than in the preceeding acylation step. Furthermore, a mechanism of reversible acylation is proposed using the PsyA ACP1-KS1 di-domain. The findings in this thesis provide important insights into mechanisms of KS specificity and show that mutagenesis can be used to expand the repertoire of acceptable substrates for future PKS engineering.
