This COVID-19 event has been created by a combination of computational inference (see https://reactome.org/documentation/inferred-events) from SARS-CoV-1 data and manual curation, as described in the summation for the overall SARS-CoV-2 infection pathway.

In the host cell cytosol the pp1a polyprotein spontaneously dimerizes. This temporary dimer has weak protease activity (Chen et al, 2010)
