\begin{Description}\relax
hgug4112aENZYME2PROBE is an R object that maps Enzyme Commission
(EC) numbers to manufacturer identifiers.
\end{Description}
\begin{Details}\relax
Each EC number maps to a named vector containing all of the
manufacturer identifiers that correspond to the gene that produces that
enzyme. The name of the vector corresponds to the EC number.

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 hgug4112aENZYME2PROBE, 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
