Constructs

Saccharomyces cerevisiae is a versatile eukaryotic model organism studied for its fermentive ability. , but its potential for synthetic biology is hidden by the lack of modular biobrick parts for this system. In addition to introducing novel genes into the registry, this year we added 3 yeast promoters, 3 yeast terminators, 2 micron origin of replication, two selectable markers, and a yeast integration plasmid suitable for future yeast work. For additional foundational tools, we have added an amber suppressor biobrick with a wide range of functionality and selectable by the amber suppressed RFP.

Yeast Regulator Biobricks

Three unique constitutive and repressible yeast promoters were introduced into the registry.

Yeast Promoters
[http://partsregistry.org/wiki/index.php?title=Part:BBa_K122000 BBa_K122000]	pPGK1	This is the 1500 bp upstream of the PGK1 coding region in an industrial yeast strain. Constitutive promoter.	1497
[http://partsregistry.org/wiki/index.php?title=Part:BBa_K122002 BBa_K122002]	pADH1	700bp upstream of ADH1 promoter region containing RBS. Constitutive promoter.	701
[http://partsregistry.org/wiki/index.php?title=Part:BBa_K122001 BBa_K122017]	pGAL1 + tetO	The GAL1 promoter which is highly repressed by glucose. An additional tetracycline operator site was included upstream of the RBS to allow repression by tetR.	484

Four additional yeast terminators were introduced into the registry.

Project Specific Constructs

This year's project involved the integration of 4-coumarate:coenzyme A ligase/ stilbene synthase fusion protein, a tyrosine ammonia lyase, and a zeocin resistance selectable marker. For more information, please visit Strategy.
