The annotation and conditions in this rule are derived from the following entries: O96007 (MOC2B_HUMAN), Q9Y8C1 (MOC2B_EMENI)

If a protein meets these conditions... i

Common conditions

    • Matches HAMAP signature MF_03052
    • taxon = Eukaryota
    • fragment ≠ the sequence is fragmented

Special conditions

    • Subsequence at position 143 - 144 aligns to "[HF]-R" in entry O96007 (individually applies "Substrate binding")
    • Subsequence at position 159 - 159 aligns to "K" in entry O96007 (individually applies "Substrate")
    • Subsequence at position 166 - 168 aligns to "K-x-E" in entry O96007 (individually applies "Substrate binding")

... then these annotations are applied i
