Reactions were assembled in a volume of 260 μl containing 50 mM Hepes buffer, 150 mM NaCl, pH 7.5 and as indicated 5 μM SrtADN in 50 mM BisTris, pH 7.5, 10 μM LPXTG peptide (DABCYL-QALPETGEE-EDANS), 10 μM TGXLP peptide (DABCYL-QATGELPEE-EDANS), 5 mM MTSET, 0.2 M NH2OH, 5 mM pHMB or 10 mM DTT. Incubations were carried out for 1 hour at 37° C. Samples were analyzed in a fluorimeter using 395 nm for excitation and 495 nm for recordings.
