physiological function | L-Thr-charged SyrB1 is the native substrate of SyrB2. Without an appended amino acid, SyrB1 does not trigger formation of the chloroferryl intermediate state in SyrB2. SyrB1 charged either by L-Thr or by any of several non-native amino acids does trigger the reaction by as much as 8000fold (for L-Thr-S-SyrB1). Triggering efficacy is sensitive to the structures of both the amino acid and the carrier protein, being diminished by 5-20fold when the native L-Thr is replaced by another amino acid and by about 40-fold when SyrB1 is replaced by a heterologous carrier protein, CytC2 | Pseudomonas syringae pv. syringae |
