Qualify xylan coculture mediation without losing utilization and enzyme gains #1637
Description
CommunityMech:000156; PMID:16348244. The three nodes and two arrows need to distinguish measured coculture outcomes from the proposed mediation by hydrogen/product removal and sugar repression. Utilization is not identical to polymer depolymerization; specific extracellular activities are protein-normalized and vary by enzyme, time and fungus. Retain the N. frontalis PNK2 outcome and canonical partners, not a blanket downgrade. Replace the enzyme-context arrow wording with the explicitly hypothesized mechanism. Close only after protected-main merge.
