Functional annotation of non-model bacteria based on sequential homology
Polakovičová, Petra ; Musilová, Jana (oponent) ; Sedlář, Karel (vedoucí práce)
The genome sequence is an essential informational resource in the field of biology and it is, therefore, a constant subject of scientific research. Bioinformatics offers computational methods for genome’s automatic analysis and processing. The bachelor thesis is dedicated to the bacterial genome, its organization, and fundamental characteristics, and subsequently description of its annotation. It mainly focuses on functional annotation (description of the biological function of predicted genes) using assignment to clusters of orthologous genes (COG) based on sequential homology. It describes the most commonly used tools and databases that use this type of annotation and then compares some of them by annotating seven bacterial genomes. Its main task is to propose a new method that improves COG annotation and makes it easy to visualize.

The COG-or: the Improved Functional Annotation of Bacterial Genomes
Polakovičová, Petra ; Sedlář, Karel
The study of bacterial organisms is given great emphasis in scientific research. By studying the bacterial genome, scientists can gain knowledge of various infectious diseases. Nowadays, it is even possible to edit genes and thus advancing the field of tailored medicine by treating many genetic diseases. Furthermore, it is becoming the norm to utilize bacteria in the industry for their ability to produce important products such as plastics, or fuels. It is therefore essential to extract the necessary information about its genes and other features. This paper focuses mainly on improving the functional annotation of bacterial genomes, classification of protein-coding sequences into clusters of orthologous groups, and visualization of the final annotated genome. For this task, the python package was developed with several functions for working with the outputs of multiple annotation tools, namely eggNOG-mapper, Operon-mapper, and Batch CD-Search. The package was tested on Clostridium diolis DSM 15410 and Clostridium beijerinckii DSM 791.
