bioannotation.py - check for properly-formed EC numbers about biocode HOT 2 CLOSED

My suggestion is to do 1.2.1 or give the option to do that, rather than automatically discard. It is less granular, but still valid e.c.

from biocode.

I checked into the code here, and the constructor method to create a bioannotation.ECAnnotation object already did have a check for the format of the passed EC number:

re_pattern = re.compile('(((([0-9\-]+)\.[0-9\-]+)\.[0-9\-]+)\.[a-z0-9\-]+)')

In that regex I noticed that I was specifically already allowing alpha-characters in the last position, but didn't remember why. So I looked into the release notes at ExPASy and found this:

ENZYME now includes entries with preliminary EC numbers. Preliminary EC numbers include an 'n' as part of the fourth (serial) digit (e.g. EC 3.5.1.n3).

Therefore, the current implementation is correct, and no changes need to be made.
