Abstract

MACiE (Mechanism, Annotation and Classification in Enzymes) is a database of enzyme reaction mechanisms, and is publicly available as a web-based data resource. This paper presents the first release of a web-based search tool to explore enzyme reaction mechanisms in MACiE. We also present Version 2 of MACiE, which doubles the dataset available (from Version 1). MACiE can be accessed from http://www.ebi.ac.uk/thornton-srv/databases/MACiE/

Growth of MACiE. This shows the growth in the number of EC codes (blue), EC sub-sub classes (cyan) and catalytic domain CATH codes (red) in MACiE.

Figure 8
Frequency distribution of amino acid residues. This shows the frequency of catalytic amino acid residues in MACiE (blue), versus the frequency of residues in MACiE (cyan), versus the frequency of residues in the wwPDB (red). The frequency of catalytic amino acid residues in MACiE is calculated by taking the number of residues (of a given type) annotated in MACiE divided by the total number of annotated residues in MACiE, multiplied by 100.
