\begin{Description}\relax
hgu2beta7ENZYME2PROBE maps Enzyme Commission numbers to probe identifiers
representing genes whose products exhibit the functions of the enzymes
labeled by the Commission Numbers
\end{Description}
\begin{Details}\relax
Enzyme Commission numbers are assigned by the Nomenclature Committee
of the International Union of Biochemistry and Molecular Biology
\url{http://www.chem.qmw.ac.uk/iubmb/enzyme/} to allow enzymes to be
identified. 

An Enzyme Commission number is of the format EC x.y.z.w, where x, y, z,
and w are numeric numbers. In hgu2beta7ENZYME2PROBE, EC is dropped from the
Enzyme Commission numbers.

Enzyme Commission numbers have corresponding names that describe the
functions of enzymes in such a way that EC x is a more general
description than EC x.y that in turn is a more general description than
EC x.y.z. The top level EC numbers and names are listed below:

EC 1 oxidoreductases

EC 2 transferases

EC 3 hydrolases

EC 4 lyases

EC 5 isomerases

EC 6 ligases

The EC name for a given EC number can be viewed at
