The initial rates of peptide/DR1 complex formation for tested peptides with and without accessory molecules.

#Initial Rates were determined for 1 hour (Response; Arbitrary Fluorescence Units min−1).*The effect of DO on HA(Y308A) was determined by using co-expressed DM/DO complex.¶Determined in a separate experiment.

# 初始速率以1小时为测定时长（响应值；任意荧光单位·分钟⁻¹）。*采用共表达的DM/DO复合物，测定了DO对HA(Y308A)的影响。¶此项测定为独立开展的实验。
