Abstract
|
|
|
|
Peroxiredoxins (Prx’s) are a superfamily of peroxidases that are ubiquitous in all super??kingdoms. Previous biochemical and structural studies have suggested that Prx’s could be divided into five subfamilies (1??Cys, Typical 2??Cys, Atypical 2??Cys C??, L????and R????types). In this work, we have developed a set of regular expression patterns describing subfamily??specific spatial constraints of the key catalytic residues. Using these patterns, 1,016 Prx’s available in public databases were classified into the five subfamilies. Our method performed well for most of the types except for Atypical 2 Cys R type.
