Free alternative to KEGG

[bsp022]

Hi, I'm trying to do some functional analysis on a metagenomic dataset and I'd like to be able to assign my hits to pathways/modules. All the papers I've seen have used KEGG for this step, but it's no longer free (unfortunately I don't have £2000 to spare!), and most of the suggested alternatives in other threads seem to be specific to model organisms.

Can anyone recommend a database of pathways suitable for use with metagenomic gene annotations?

for metagenome functional analysis, you can try FOAM http://portal.nersc.gov/project/m1317/FOAM/
