The annotation and conditions in this rule are derived from the following entries:
Q9X0C7 (HIS4_THEMA), P16250 (HIS4_STRCO), P9WMM5 (HIS4_MYCTU)
If a protein meets these conditions...

Common conditions
Special conditions
- Subsequence at position 8 - 8 aligns to "[DE]" in entry Q9X0C7 (individually applies "Proton acceptor")
- Subsequence at position 127 - 127 aligns to "[DE]" in entry Q9X0C7 (individually applies "Proton donor")
... then these annotations are applied
