This volume presents detailed protocols for novel strategies and approaches to improve functional understanding of protein N- and C-terminal biology. Protein Terminal Profiling: Methods and Protocols addresses topics such as protease specificity profiling, N-terminal acetylation, assays to probe protease activity in cellular systems, protein N- and C-termini on a proteome-wide scale, and biochemical approaches to explain and examine extracellular protease activities. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls.
