The method uses local sequence alignments (BLAST) to find similar sequences (potential homologs) for one or several input sequences. The program extracts all GO terms associated to each of the obtained hits and returns an evaluated GO annotation for the query sequence(s). Enzyme codes are obtained by mapping from equivalent GOs while InterPro motifs can directly be queried at the InterProScan web service. A basic annotation process with Blast2GO PRO consists of 3 steps: blasting, mapping, and annotation. These steps are described in the manual including further explanations and information on additional functions.
