We're working on it... come back in a few decades for an answer.
Projects like sequencing 1.2 million new genes/proteins 
from over 1800 species in the Sargasso Sea will get us there faster:

Or if you just want a list of cataloged proteins, see

If you want to estimate the number of proteins in nature,
first estimate the number of species in nature (10-30 million), 
then multiply by a factor around 10,000 to 40,000 proteins/species 
for eukaryotes, under 5000 for smaller things, and adjust for a 
portion of identical proteins (maybe 1/3 to 2/3) per species.
