An R object that contains information on Enzyme Commission terms. These
terms are organised as a direct acyclic graph (DAG), which is further
stored as an object of the class 'igraph' (see
http://igraph.org/r/doc/aaa-igraph-package.html). Enzyme
Commission (EC) is a resource focused on enzyme nomenclature, which is
a system of naming enzymes (protein catalysts) with Cross-references to
UniProt sequences. It uses four-digit EC numbers to define the reaction
catalysed. The first three digits are to define the reaction catalysed
and the fourth for a unique identifier (serial number).
Usage
data(obo.EC)
Arguments
Value
an object of class "igraph". As a direct graph, it has attributes to
vertices/nodes:
vertex attributes: "name" (i.e. Term ID), "term_id" (i.e.
Term ID), "term_name" (i.e. Term Name), "term_namespace" (i.e. Term
Namespace), and "term_distance" (i.e. Term Distance: the distance to
the root; always 0 for the root itself)
