In the case of TIM, structural dynamics are known to be essential to function. In particular the stabilization of the binding pocket by a phosphodianion “handle” of the substrate and the closing of catalytic site loops 6 and 7 over the substrate. Loop 6 moves by as much as 7 Angstroms with binding. Recently a mutant survey for human TIM (hsTIM) found kcat can change significantly for a single mutation distant from the catalytic site. Crystallographic measurements find no structural change with the mutation, suggesting a dynamical mechanism for the allosteric effect. Here we use Stationary Sample Anisotropic Terahertz Microscopy (SSATM) to measure the long-range intramolecular vibrations and determine if specific vibrations couple the allosteric and catalytic sites. SSATM isolated protein long-range structural vibrations based on the dominant displacement direction [1-4]. We examine if specific vibrational bands are associate with loop 6 and loop 7 flexibility.&lt;/p&gt;</style></abstract><work-type><style face="normal" font="default" size="100%">Meeting Abstract</style></work-type><accession-num><style face="normal" font="default" size="100%">WOS:000513023201285</style></accession-num><notes><style face="normal" font="default" size="100%">ISI Document Delivery No.: KK8YX&lt;br/&gt;Times Cited: 0&lt;br/&gt;Cited Reference Count: 4&lt;br/&gt;Cited References: &lt;br/&gt;     Acbas G, 2014, NAT COMMUN, V5, DOI 10.1038/ncomms4076&lt;br/&gt;     Niessen K.A.
