However, during structure calculation, GLU10 was labeled as GLN10 to construct the macrocycle for convenience. GLN10 was kept in the final coordinate file and chemical shift file for consistency. The actual sequence is still: EMRLS(DPP)FFR(GLU)FILQRKK Source: (synth.) Streptococcus pneumoniae (bacteria) / References: UniProt: P60242 |
