Figure 5: Predicted peptidases and amino acid transporters recovered from the MAGs.

(a) Number (bubble diameter) and relative gene expression (bubble colour intensity) of selected peptidases possibly involved in EPS matrix protein degradation. Peptidases were annotated against the MEROPS database⁶⁶. The subcellular location (extracellular, outer membrane or peroplasm) of each peptidase was predicted using the subcellular localization predictor (CELLO)⁶⁹. A summary of all predicted peptidases can be found in Supplementary Data 5. (b) Number (bubble diameter) and relative gene expression (bubble colour intensity) of amino acid and peptide transporters predicted across the recovered genomes. Transporters were annotated against the transporter classification database (TCDB)⁷⁰ and can be found in Supplementary Data 2.
