The import of peroxisomal matrix proteins is dependent on one of two targeting signals, PTS1 and PTS2. We demonstrate in vivo that not only the import of thiolase but also that of a chimeric protein consisting of the thiolase PTS2 (amino acids 1-18) fused to the bacterial protein beta-lactamase is Pas7p dependent. In addition, using a combination of several(More)
Methylmalonic aciduria and homocystinuria, cblC type, is the most common inborn error of cellular vitamin B12 metabolism. We previously showed that the protein carrying the mutation responsible for late-onset cblC (MMACHC-R161Q), treatable with high dose OHCbl, is able to bind OHCbl with wild-type affinity, leaving undetermined the disease mechanism(More)
