Abbr	= organism abbreviation 
Prots	= no. predicted proteins in genome
Matched	= no. proteins with structural assignment
%Prots	= percentage proteins with structural assignment
%aa	= percentage residues with structural assignment
No. dom	= no. structural domains assigned
No. SFS	= no. superfamilies assigned
Doms/SF	= average no. domains per superfamily
DupLev	= duplication level; (no. domains - no. superfamilies)/no. domains
AvLen	= average length of a predicted protein in residues
AvDomLen= average length of an assigned domain in residues
