Isotopes in geobiochemistry: tracing metabolic pathways in microorganisms of environmental relevance with stable isotopes.

abstract：:Semisynthesis is used to create defined analogues of proteins by the chemical manipulation of peptide fragments largely derived from the natural protein and the subsequent reassembly of those fragments into a near-native conformation. In common with the total synthesis of proteins, it requires efficient and non-destru...
