Technical Abstract: We are assembling a workcell to conduct plasmid-based functional proteomics for the optimization of protein open reading frames (ORF) and for screening of improved yeast and bacterial strains. For this project a liquid handler was designed and assembled onto the Sias Xantus platform so that a Hudson Control Group track component could be placed within the Xantus gripper tool work area for generating plasmids using the Qiagen Turbo plasmid preparation kit, which gives four 96-well plates of plasmids in one run. In generating this set of plasmids, 20 ug of 96 different clones or up to 5 ug of 384 individual clones can be obtained. Methods were developed for the workcell using the plasmids generated to evaluate their quality. As an example using these methods, a mutgenesis strategy was designed for the cellulase F ORF from Orpinomyces, and an optimized mutant was identified. The plasmids obtained were used in sequencing reactions, in vitro transcription/translation, and transformation of BL21 DE3 expression bacteria, as well as transformation of yeast strains for scale up of expressed protein and for AZO-cellulose plate assays. The liquid handler was found to provide sufficient plasmid DNA for all methods to be used on the workcell including a routine for multiplex sets of plasmid that were expressed in vitro and in vivo.
