All the predicted proteins from the X. index, Mesodorylaimus sp. YZB2_4, Trichinella spiralis, Trichinella nelsoni, Trichuris muris, and Trichuris trichiura genomes were compared with entries in the CAZy database (Drula et al., 2022). A homemade pipeline combining the BlastP (https://blast.ncbi.nlm.nih.gov/Blast.cgi) and HMMER3 (http://hmmer.janelia.org/) tools was used to compare protein models with the sequences of the CAZy modules. Proteins with E-values less than 0.1 were further screened by a combination of BlastP searches against libraries generated from the sequences of the catalytic and non-catalytic modules. HMMER3 was used to search against a collection of custom Hidden Markov Model (HMM) profiles constructed for each CAZy family. Expert curators then performed manual inspection to resolve borderline cases.
