Título: Cloning and expression of S-Adenosyl Methionine Synthetase gene in recombinant E. coli strain for large scale production of SAMe
Fonte: Electron. j. biotechnol;13(4):1-2, July 2010. ilus, tab.
Idioma: en.
Resumo: S-Adenosyl Methionine (SAMe) Synthetase is an enzyme which catalyses the synthesis of S-Adenosyl Methionine using methionine and ATP. It is also known as AdoMet which is well known methyl donor, which modifies DNA, RNA, histones and other proteins, dictating replicational, transcriptional and translational fidelity, mismatch repair, chromatin modeling, epigenetic modifications and imprinting. The objective of the present work is to clone the SAMe Synthetase gene in recombinant E. coli strain in order to express, characterize and purify it for further synthesis of SAMe in a large scale fermentation. Expression was induced by 1 mM IPTG and expressed protein was characterized by SDS-PAGE. The recombinant E. coli cells were used for the production of SAMe through batch and fed batch fermentation operations. The produced SAMe was purified through paper chromatography in order to use it in our future studies.
