Pupylation site databases | Post-translational modification data analysis
Prokaryotic ubiquitin-like protein (Pup), the firstly identified post-translational protein modifier in prokaryotes, is an important signal for the selective degradation of proteins. Recently, large-scale proteomics technology has been applied to identify a large number of pupylated proteins.
Provides access to data about protein lysine modification. PLMD allows users to search through an interface containing more than 280 000 modifications events in more than 53 000 proteins across 176 eukaryotes and prokaryotes for up to 20 types of protein lysine modifications (PLMs). Its configuration permits to explore contents using several filters such as modification types, species numbers, or protein numbers.
A database of pupylated proteins and pupylation sites aiming to provide an easily accessible web service for the analysis of pupylated proteins. Hyperlinks to major protein, structure and annotation databases are provided for accessing related information. Four useful tools are constructed and integrated into PupDB to provide functions of browses, keyword searches, sequence similarity searches and interactive displays of protein structures. Currently, PupDB contains 268 pupylated proteins with 311 known pupylation sites and 1123 candidate pupylated proteins.
