Whole genome sequencing for "P. patoris" had been performed. The "P. pastoris" GS115 genome has been sequenced by the Flanders Institute for Biotechnology and Ghent University, and published in "Nature Biotechnology". The genome sequence and gene annotation can be browsed through the ORCAE system. The complete genomic data allows scientists to identify homologous proteins and evolutionary relationships between other yeast species and "P. pastoris". Furthermore, "P. pastoris" are single eukaryotic cells, which means researchers could investigate the proteins inside "P. pastoris". Then the homologous comparison to other more complicated eukaryotic species can be processed, to obtain their functions and origins.
