Post-Translational Modification Site Prediction Service
Identifying modification sites at residue-level resolution is fundamental for understanding cellular regulation. Experimental methods such as mass spectrometry provide accurate detection but require significant time, resources, and technical expertise. Computational prediction has emerged as a powerful complement. By leveraging bioinformatics approaches, researchers can generate hypotheses about likely PTM sites, prioritize experiments, and gain insight into modification dynamics.

Services at MtoZ Biolabs
MtoZ Biolabs provides an integrated suite of bioinformatics-driven analyses to support PTM research. Our post-translational modification site prediction service covers the full data-to-insight pipeline.
1. Residue-Level PTM Prediction
We provide predictions of modification sites across multiple PTM types, including both well-characterized modifications such as phosphorylation and acetylation and less common forms such as crotonylation or neddylation. Each predicted site is reported with residue position, modification type, and confidence score, generated through validated bioinformatics algorithms.
2. Motif and Enzyme Analysis
We analyze sequence motifs surrounding predicted sites to identify conserved sequence patterns and infer upstream regulators. By combining motif detection with enzyme-substrate knowledge bases, we predict likely kinases, phosphatases, acetyltransferases, and ubiquitin ligases responsible for site-specific regulation.
3. Functional Annotation
Predictions are contextualized with domain annotation, secondary structure predictions, solvent accessibility, and protein–protein interaction interfaces. This bioinformatics annotation ensures that results are not just lists of residues but are mapped to biological functions.
4. Comparative and Evolutionary Prediction
We perform conservation analysis across orthologs and species to highlight modification sites that are evolutionarily maintained or divergent. This enables researchers to distinguish regulatory "hot spots" from species-specific variation.
5. Differential Prediction and Integration
For clients with experimental datasets, we integrate prediction results with observed spectra to highlight condition-specific modifications. This hybrid strategy connects bioinformatics models with empirical data for maximum reliability.
6. Pathway and Network Analysis
Predicted PTM sites are incorporated into protein interaction networks and signaling pathways using curated bioinformatics databases. This systems-level analysis shows how predicted modifications may rewire cellular regulation.
