Peb1p (Pas7p) is an intraperoxisomal receptor for the NH2-terminal, type 2, peroxisomal targeting sequence of thiolase: Peb1p itself is targeted to peroxisomes by an NH2-terminal peptide.

Abstract excerpt

Peb1 is a peroxisome biogenesis mutant isolated in Saccharomyces cerevisiae that is selectively defective in the import of thiolase into peroxisomes but has a normal ability to package catalase, luciferase and acyl-CoA oxidase (Zhang, J. W., C. Luckey, and P. B. Lazarow. 1993. Mol. Biol. Cell. 4:1351-1359). Thiolase differs from these other peroxisomal proteins in that it is targeted by an NH2-terminal, 16-amino...
