It catalyzes the oxidative demethylation of trimethylamine to dimethylamine and formaldehyde. Initial work focused on developement of a recombinant expresion system for TMADH. With the development of this system, work has focused on a variety of residues in the active site of the enzyme. In collberation with Dr R Silverman, we have investigated the source of oxygen in 6-OHFMN formation, rendering the protein inactive. We have shown that Tyr-60 is not acting as an active site base in TMADH. We have identified a role for Phe-130, that of governing access into the active site of TMADH 2005-04-19 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1111429788 http://rave.ohiolink.edu/etdc/view?acc_num=osu1111429788 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
