The annotation and conditions in this rule are derived from the following entries: P68567 (RSMJ_ECOLI), Q7UAV7 (RSMJ_SHIFL)

If a protein meets these conditions... i

Common conditions

    • Matches HAMAP signature MF_01523
    • taxon = Bacteria
    • fragment ≠ the sequence is fragmented

Special conditions

    • Subsequence at position 101 - 102 aligns to "R-[DE]" in entry Q7UAV7 (individually applies "S-adenosyl-L-methionine binding")
    • Subsequence at position 117 - 118 aligns to "[ED]-R" in entry Q7UAV7 (individually applies "S-adenosyl-L-methionine binding")
    • Subsequence at position 153 - 154 aligns to "S-S" in entry Q7UAV7 (individually applies "S-adenosyl-L-methionine binding")
    • Subsequence at position 171 - 171 aligns to "[DE]" in entry Q7UAV7 (individually applies "S-adenosyl-L-methionine")

... then these annotations are applied i

Protein namei

  • Recommended name:
