qPTMplants

qPTMplants aggregates quantitative post-translational modification (PTM) data in plants to enable analysis of PTM occurrence and dynamics across species and experimental conditions.

Key Features:

• Data scale: Contains 1,242,365 experimentally identified PTM events on 429,821 nonredundant sites from 123,551 proteins.
• Quantitative coverage: Provides quantification for 620,509 events across 136,700 PTM sites on 55,361 proteins under 354 distinct conditions.
• PTM and species diversity: Documents 23 types of PTMs across 43 plant species and 583 conditions.
• Provenance: Assembled from 293 published studies.
• Experimental detail curation: Manually curates experimental metadata including conditions, samples, instruments, and methods.
• Source technology: Data are derived from mass spectrometry-based proteomic technologies.
• Annotations: Integrates sequence and structural characteristic annotations for PTM sites.

Scientific Applications:

• PTM profiling: Enables large-scale identification and cataloging of PTM sites and events across plant proteomes.
• Quantitative dynamics: Supports analysis of condition-specific and dynamic regulation of PTMs under diverse experimental conditions.
• Comparative studies: Facilitates cross-species comparison of PTM patterns among 43 plant species.
• Proteomic research: Provides curated, mass spectrometry-derived data and annotations for downstream proteomic and structural analyses.

Methodology:

Data were compiled from 293 published, mass spectrometry-based proteomic studies, manually curated for experimental details (conditions, samples, instruments, methods), and integrated with sequence and structural characteristic annotations.
