Supplementary data for: Novel putative PETase candidates from metagenomic mining of Ébrié lagoon and Kassembié lake, Côte d'Ivoire

This dataset contains the supplementary material supporting the article "Novel putative PETase candidates from metagenomic mining of Ébrié lagoon and Kassembié lake, Côte d'Ivoire" (Access Microbiology).

Shotgun metagenomes from two Ivorian aquatic sites (Biétry Bay in the Ébrié lagoon (Abidjan) and Lake Kassembié (Alépé)) were used to describe microbial community structure and to mine for plastic-degrading enzymes. Four putative PET hydrolases, designated BietPETase1 to BietPETase4, were identified and structurally compared with the Ideonella sakaiensis PETase (PDB 6EQE).

Contents of the archive:

Table S1 : reference database of 158 non-redundant characterised PET-degrading and plastic-active enzyme sequences, compiled from PAZy, NCBI, BRENDA and UniProt and clustered at 95% identity with CD-HIT v4.8.1, together with the source record (accession, source database, enzyme, organism and published reference) for each sequence.

Table S3 : per-MAG genome quality for the 49 dereplicated metagenome-assembled genomes: completeness and contamination from CheckM2 v1.1.0 with the MIMAG quality tier, and taxonomy from GTDB-Tk v2.4.0 (release r226).

Supplementary Data S1 : amino-acid sequences of the four putative PETase candidates (BietPETase1–4) with their MAG of origin.

Supplementary Data S2 : the four three-dimensional models predicted with ColabFold v1.6.1 (AlphaFold2) in PDB format, with per-residue pLDDT stored in the B-factor column, together with the IsPETase reference structure (PDB 6EQE) used for the TM-align comparison.

Processed annotation and figure data, each file prefixed with the tool that produced it: dbCAN2 (CAZyme classes per MAG), KofamScan v1.3.0 (gene-to-KO assignments and validated KO hits), MetaPhlAn4 (relative-abundance matrices and log2 fold-change tables) and Kraken2 (species richness per sample).

A README.md file in the archive documents every file, the tool and version that generated it, and the corresponding figure or table in the article.
