Improve the function of an existing BioBrick part or device:

We improved the standard iGEM shipping plasmid pSB1C3 by creating modified version to allow the easy conversion of Golden Gate standard parts to BioBrick parts. We submitted three plasmids, one each for converting promoters, coding sequences, and terminators. This will allow other teams to take advantage of the Golden Gate standard and also easily submit BioBricks.

Collaboration with the Dalton High School iGEM team:

A former PhD student at Johns Hopkins University and a current high school science teacher and iGEM advison at the Dalton School in New York City, Dr. Jennifer Hackett approached the Hopkins wetware iGEM team to discuss a mutual interest in characterizing yeast promoters. As a result of this conversation, we suggested that as one component of the Dalton School's iGEM project, Dr. Hackett could implement both our Parts Course as well as our Yeast Transcriptional Unit Assembly Standard (RFC88). In brief, we suggested that the Dalton team could subclone a series of yeast promoters, flanked by BsaI sites and our signature overhang sequences, so they could efficiently and directionally assembly these promoters upstream of genes encoding different fluorescent proteins. As part of this collaboration, we selected ~30 yeast promoter sequences for the Dalton team to clone. Promoters were chosen if they could be induced (e.g. by temperature or sugar source), or would drive expression of the downstream fluorescent protein with varying strengths. The Dalton School had a successful project and were able to clone almost the entire set of promoters. They are now working on assembling transcriptional units and testing the effects of the different promoters.

Collaboration with the John Hopkins Software Team:

The second of our collaborations was with our colleagues on the Johns Hopkins software team. They developed AutoGene, "an all-encompassing plasmid design suite meant to streamline the process of both annotating and building sequences." We sent them several plasmid sequences and they returned the annotated plasmids. We then provided feedback to the software team on the performance of AutoGene. This collaboration was beneficial to the JHU Software team as our requests and user feedback helped them to develop AutoGene.

Outline and detail a new approach to an issue of human practice in synthetic biology:

We designed a synthetic biology lab manual to be used in introductory biology lab courses.

Demonstrate that at least one new biobrick part or device of your own design and construction works as expected:

We showed that our ethanol-induced promoters showed different responses to ethanol. We showed that our CYP2E1 expressing yeast strains lowered the concentration of ethanol over a 24 hour fermentation. We showed that our Golden Gate to BioBrick conversion vectors could easily convert our Golden Gate promoters, coding sequences, and terminators to the BioBrick standard for submission to the Registry.

Characterize the operation of at least one new Biobrick part or device and enter this information in the "main page" section of that part's registry entry:

We characterized the operation of our ethanol-induced promoters by using them to express GFP under different ethanol concentrations. We measured the effect of CYP2E1 expression under ethanol-induced and constitutive promoters on the ethanol concentration during fermentation.
