Autophagy (Apg) and … WebApr 2, 2010 · Yeast cells also have the cytoplasm to vacuole targeting (Cvt) pathway. The Cvt pathway is responsible for the delivery of at least two hydrolases, α-mannosidase (Ams1) and aminopeptidase I (Ape1), to the vacuole. Ape1 is synthesized in the cytosol as a proenzyme that is relatively inactive.

Cytoplasm-to-vacuole targeting (Cvt) is an autophagy-related pathway in yeast. Under vegetative conditions it delivers hydrolases, such as aminopeptidase 1 (Ape1), to the vacuole. This makes the cvt pathway the only known biosynthetic pathway to utilize the machinery of autophagy for operation.
