autocatalysis

 [aw″to-kah-tal´ĭ-sis]
an increase in the rate of a chemical reaction in which a product of the reaction itself hastens or intensifies the rate.

au·to·ca·tal·y·sis

(aw'tō-kă-tal'i-sis),
A reaction in which one or more of the products acts to catalyze the reaction; after beginning slowly, the rate of such a reaction rapidly increases. Compare: chain reaction.
Synonym(s): autoactivation

The other variant is a C-terminal nonsense mutation (PCSK9-C679X) that causes the retention of autocatalytically cleaved PCSK9 in the ER (16, 21).
In addition, MJ appears to affect its own (and JA's) biosynthesis autocatalytically. Airborne jasmonate molecules are thought to enter the plant either through the stomata or by diffusing into the leaf cell cytoplasm (Farmer and Ryan 1990).

The polyproteins are autocatalytically processed into replicative enzymes, including the RNA-dependent RNA polymerase, which synthesizes both negative-sense and positive-sense sgRNAs, and the positive-sense sgRNAs serve as mRNAs for all of the open reading frames (ORFs) downstream of ORF1b (6,11).
