What is a CGC?

A carbohydrate-active enzyme gene cluster (CGC) is a run of co-localized genes containing at least one CAZyme or sulfatase together with its neighbours — transporters, peptidases, sigma/anti-sigma factors, transcriptional regulators — as predicted by dbCAN's CGCFinder. The CGC is the atomic unit of mpCGCdb: every enzyme family, community, and taxonomy view on this site is an aggregation over these clusters.

Find a CGC

Individual CGCs are not in the top-bar search. Jump straight to one by ID:

IDs are case-sensitive and follow the pattern <MAG_id>_CGC<n> · stable URL: https://mpcgcdb.com/cgcs/<cgc_id>/

Or browse into CGCs by context:

By MAG	All MAGs → a MAG page → its CGC table → click a row
By enzyme family	CAZyme / sulfatase family → CGCs carrying that family
By taxonomy	GTDB tree → a taxon → its CGCs
