Thiol

... the resulting thioester (citryl-CoA) so the net reaction is the transfer of an acetate group to oxaloacetate removing the CoA in the process. The thiol activates in two senses: it enhances the rate of enolization (the methyl protons of the thioester are more acidic than a simple ester); and preferentially ...

... See http://www.chem.qmul.ac.uk/iubmb/enzyme/EC2/1/1/67.html There is another enzyme, EC 2.1.1.9 with a similar name, but it has a broader range of thiol acceptors compared to EC 2.1.1.67 (TPMT). You can check out this kind of information from either the Enzyme Commission web site, or the Expasy ...

... and bacteria.. I was wondering how sulphate kicks 2 of the phosphate group off and get attached to ATP to form APS.... and also how O-acetylserine thiol-lyase work. I dont know how SH kick out acetate group and get attatched to form cysteine.. plz help me out. Im new to biochem... thanx in advance

... while ago. We need to some calculations and answer some questions concerning the practical. One question is to calculate the number of reactive thiol groups in one molecule of the protein. No matter how much I have tried I can't figure out how to do this. We were given the molecular weight of ...
