The putative annotation which was initially provided ''on the basis of...'' prompted a literature search using the term 'arylformamidase'. Pabarcus et al. (2007) have analysed the function of an arylformamidase present in the liver of ''Mus musculus''.
- Screening of BLAST result (see Sebastien) for functional information.
Ironically, from the BLAST results, the most similar sequence to 2pbl for which there was functional information available was the arylformamidase characterised by Pabarcus et al. 2007. Using site-directed mutagenesis, a catalytic triad was identified - S162, D247 and H279. To elucidate any functional similarity between arylformamidase and 2pbl, conservation of the catalytic triad was assessed through a clustalW alignment (see figure ...). Both S162 and H279 were found to be conserved in relatively conserved regions of the alignment whereas D247 had undergone a semi-conserved substitution. These residues correlated to... The residues were located on the tertiary structure of 2pbl and determined to be sufficiently proximal to one another to permit catalysis (see figure...).
