The QM methodologies range from ab initio techniques to density functional theory (DFT), to various semi-empirical quantum mechanical (SQM) schemes. Many computational methods have been employed over the last decades, including cluster modeling using quantum mechanics (QM), quantum mechanics/molecular mechanics (QM/MM), and QM/MM implemented with molecular dynamics (MD). Contemporary computational methods are elegant tools to address these challenges, interpreting, and complementing experimental information to suggest mechanistic details, provided the quantitative properties are in sufficient agreement with experimental observations. Although experimental observations, including crystal and solution structures, conformations, spectroscopy, and kinetics, have provided mechanistic insight, enzymes remain highly challenging and are a topic of continued discussion.
They also represent a key, challenging subfield at the forefront of theoretical and computational chemistry. Proteins, in general, and enzymes, in particular, play key roles in chemical and biological processes.

You should get enough data so as to have 3 or 4 values of v o, both above and below the K M value. Record the values of and v o you obtain then graph them on a double reciprocal plot to determine K M and V max. Tabbing out of the entry slot or clicking anywhere on the page will also calculate v o.)ģ. (Each calculated v o value has a small "experimental error" added to it. We want to determine V max and K M by measuring the dependence of the initial velocity on the substrate concentration. , where v o = the initial velocity V max = the maximal velocity = the substrate concentration K M = at half-maximal velocity, i.e.the Michaelis constant.
