In this website we create a simple platform to view the results of HHSearch (Steinegger et al., 2019) for all yeast proteins and their similarity predictions to all organisms. HHSearch is a powerful engine that was optimized to predict similarity based on amino acid sequence and secondary structure predicted from the amino acid sequence.

In this database, for each yeast protein we also present protein descriptions from UniProt (UniProt Consortium, 2021), Pfam (Mistry et al., 2021), Pdb70 (Berman et al., 2000), scop (Andreeva et al., 2014, 2020). and links to the respective databases. In addition, for relevant cases we added information regarding their involvement in disease (Rappaport et al., 2017) and/or their enzymatic activity (Chang et al., 2021).

Protein sequences for all saccharomyces cerevisiae genes were obtained from SGD (Cherry et al., 2012) and rearranged to individual FASTA file formats using a homemade script. The individual FASTA files were submitted to a standalone HHSearch (from hhsuite3) (Steinegger et al., 2019) and searched against Pdb70 (Berman et al., 2000), PfamA V34 (Mistry et al., 2021), scop70-1.75  and scop40 (Andreeva et al., 2014, 2020). All proteins with the word “dubious” in their description were discarded, as well as hits with similarity score below 95 (out of 100). The result files were combined to a single .csv file using a homemade script. If the match was through a PDB structure, the host organism was added from the PDB description. Further information for each protein was added from UniProt (UniProt Consortium, 2021) , including the indicated EC numbers (McDonald et al., 2001). Additionally, the involvement of each human similar protein with specific diseases was added based on a MalaCards search (Rappaport et al., 2017) conducted on GeneCards (Stelzer et al., 2016) version V4.13 on February 26th, 2020. Further analyses were performed on this assembled database, from here on termed, AnalogYeast, using homemade scripts(
