ready Enzyme Commission Number

Abbreviation: EC Number


General Information
In its report in 1961, the first Enzyme Commission devised a system for enzyme classification that also serves as a basis for assigning code numbers. These code numbers, prefixed by EC, contain four elements separated by points / full stops and are now widely in use. The first number shows to which of the six main divisions (classes) the enzyme belongs and therefore identifies the class of reaction catalysed. The second number indicates the subclass, and generally contains information about the type of compound or group involved. The third figure gives the sub-subclass, which further specifies the type of reaction involved. The fourth figure is the serial number of the enzyme in its sub-subclass.

TIGRFAMs
TIGRFAMs is a collection of manually curated protein families focusing primarily on prokaryotic sequences.It consists of hidden Markov models (HMMs), multiple sequence alignments, Gene Ontology (GO) terminology, Enzyme Commission (EC) numbers, gene symbols, protein family names, descriptive text, cross-references to related models in TIGRFAMs and other databases, and pointers to literature. Originally developed at The Institute for Genomic Research (TIGR) and later at its successor, the J. Craig Venter Institute (JCVI), it is now maintained by the NCBI.

ExplorEnz
The Enzyme Database was developed as a new way to access the data of the IUBMB Enzyme Nomenclature List. The data, which are stored in a MySQL database, preserve the formatting of chemical names according to IUPAC standards.

Enzyme nomenclature database
ENZYME is a repository of information relative to the nomenclature of enzymes. It is primarily based on the recommendations of the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology (IUBMB) and it describes each type of characterized enzyme for which an EC (Enzyme Commission) number has been provided. The database is complete and up to date. It is regularly updated to reflect updates and additions to the nomenclature.

DES-TOMATO
DES-TOMATO is a topic-specific literature exploration system developed to allow the exploration of information related to tomato. The information provided in DES-TOMATO is obtained through the text-mining of available scientific literature, namely full-length articles in PubMed Central and titles and abstracts in PubMed.
