IIRC, they are engineering yeast to produce the appropriate proteins.
Biosynthesis is far more efficient for manufacturing these types of
compounds than laboratories will be for a good many years. Biosynthesis of
natural proteins also allows faster time to market, especially with recent
improvements in biotech. Engineering a commercial-grade process for
complex organics can take much longer than hijacking existing bio-machinery.
