摘要：
In the past decade, much progress has been made in understanding the mechanisms that govern sorting of proteins to the peroxisomal lumen. This article summarizes the principal features of how peroxisomal matrix enzymes are thought to reach the peroxisome. In addition, it describes recent data that indicate that, in specific pex mutants of the methylotrophic yeast Hansenula polymorpha, defects in matrix protein import can be (partly) rescued by overproduction of the receptor essential for import of these proteins. The implication of these results on the mechanisms of matrix protein import is discussed.
