AMAPEC: A computational tool to predict antimicrobial activity in effector proteins

AMAPEC is a machine learning framework developed in the Thomma lab to predict antimicrobial activity in fungal secreted effector proteins. The tool addresses a key limitation in effector biology: the lack of methods tailored to large, structurally diverse fungal effectors, which are poorly captured by classical antimicrobial peptide predictors.

Unlike peptide-focused approaches, AMAPEC is trained on a curated dataset of experimentally validated antimicrobial proteins, explicitly designed to accommodate the size and complexity of fungal effectors. It integrates sequence-derived features, physicochemical properties, and structure-informed descriptors to classify proteins based on their likelihood of antimicrobial activity.

AMAPEC thereby provides a scalable framework to explore antimicrobial effector repertoires and to generate hypotheses on how fungi shape their biotic environments through secreted proteins.
