BLASTP bit-score

Accession MO:0000029
DefinitionA score is a numerical value that describes the overall quality of an alignment with higher numbers correspond to higher similarity. The bit-score (S) is determined by the following formula: S = (λ × S − lnK)/ ln2 where λ is the Gumble distribution constant, S is the raw alignment score, and K is a constant associated with the scoring matrix. Many AMR detection models use this parameter, including the protein homolog and protein variant models. The BLASTP bit-score parameter is a curated value determined from BLASTP analysis of the canonical reference sequence of a specific AMR-associated protein against the database of CARD reference sequence. This value establishes a threshold for computational prediction of a specific protein amongst a batch of submitted sequences.
