ACKNOWLEDGMENTS We are grateful for support from The Research Council of Norway (FRIPRO program to P.B.P.: 250479; BIONÆR program to B.W.: 244259), the European Research Commission Starting Grant Fellowship (awarded to P.B.P.; 336355 MicroDE), and the Scottish Government Rural and Environmental Sciences and Analytical Services (RESAS) (for P.L. and S.H.D.). S.L.L.R. generated constructs and performed recombinant protein production and purification and functional characterizations of the binding protein and GHs. L.J.L., S.L., and L.M. expressed, purified, and performed functional characterization of FpCE2 and FpCE17. Growth experiments on mannans and SCFA quantifications were performed by G.L. ITC was performed by Å.K.R., Z.L., and L.S.M. G.V.P. and S.L.L.R. conducted the human metagenomic analysis. S.L.L.R., P.B.P., and B.W. conceived the study and supervised research. The manuscript was written primarily by S.L.L.R. with contributions from P.B.P., S.H.D., G.L, L.M., S.L., G.V.P., E.C.M., L.S.M., B.W., and L.J.L. Figures were prepared by S.L.L.R. We declare that we have no competing interests.
