The annotation and conditions in this rule are derived from the following entries:
P13029 (KATG_ECOLI), O59651 (KATG2_HALMA), Q939D2 (KATG_BURPS), P9WIE5 (KATG_MYCTU), Q31MN3 (KATG_SYNE7)

Common conditions
- Matches HAMAP signature MF_01961
- taxon = Bacteria
- fragment ≠ the sequence is fragmented

Special conditions
- Subsequence at position 226 - 252 aligns to "Y-x*-M" in entry P13029 (individually applies "Tryptophyl-tyrosyl-methioninium (Tyr-Met) (with @RESIDUE_NAME_AT_POS|Trp|105|@)")
- Subsequence at position 106 - 106 aligns to "H" in entry P13029 (individually applies "Proton acceptor")
- Subsequence at position 102 - 102 aligns to "R" in entry P13029 (individually applies "Transition state stabilizer")
- Subsequence at position 105 - 226 aligns to "W-x*-Y" in entry P13029 (individually applies "Tryptophyl-tyrosyl-methioninium (Trp-Tyr) (with @RESIDUE_NAME_AT_POS|Met|252|@)")
- Subsequence at position 267 - 267 aligns to "H" in entry P13029 (individually applies "Iron (heme axial ligand)")
