Activating Compound

Activating Compound Comment Organism Structure
additional information peptone up-regulates expression of the aaoSo gene Streptococcus cristatus

Application

Application Comment Organism
additional information LAAO contributes to competitive edge of Streptococcus oligofermentans over Streptococcus mutans in mixed-species biofilm with peptone Streptococcus cristatus

Cloned(Commentary)

Cloned (Comment) Organism
overexpressed in Escherichia coli BL21(DE3)pLysS Streptococcus cristatus

Protein Variants

Protein Variants Comment Organism
additional information an aaoSo mutant loses H2O2 formation from L-amino acids. Inhibition by Streptococcus oligofermentans of Streptococcus mutans in a peptone-rich mixed-species biofilm is greatly reduced Streptococcus cristatus
