Mechanism and evolutionary divergence of a novel oxidized polyvinyl alcohol hydrolase in Stenotrophomonas rhizophila QL-P4

Key Points

• The mechanism of oxidized polyvinyl alcohol hydrolase exhibits unique features that differ from known enzymes.
• Key findings indicate significant divergence in enzyme function compared to its homologs in other species.
• Analysis of protein sequences showed variations that suggest adaptation to environmental conditions.
• Further studies may enable the use of this enzyme in wastewater treatment and plastic pollution management.
