Determination of the pH threshold for sTva-induced conformational change in ALV-A TM. RCASBP(A)-EGFP virus was incubated with or without 20 nM sTva in the presence of 100 μM EDTA and 1.1 mM CaCl2 at the indicated pHs and analyzed by TMCA as described in the legend to Fig. 4. Only the 90-kDa species of TM is shown.
