Q9BYV7
Morphology
point mutation at nucleotide position 837,806 that is predicted to be a nonsynonymous mutation in the exon 9 of the BCO2 gene. This variant results in the substitution of a histidine for an arginine at residue 413 of the protein (R413H) . In silico analysis suggests that the R413H could cause structural distortion of the protein and lead to a possible loss of activity. In vitro assays with the urucum BCO2 variant show that the enzyme activity is lost. N
