The annotation and conditions in this rule are derived from the following entries: P16456 (SELD_ECOLI)

If a protein meets these conditions... i

Common conditions

Special conditions

    • Subsequence at position 17 - 17 aligns to "[CU]" in entry P16456 (individually applies "")
    • Subsequence at position 20 - 20 aligns to "K" in entry P16456 (individually applies "Important for catalytic activity")
    • Subsequence at position 230 - 236 aligns to entry P16456 (individually applies "ATP")

... then these annotations are applied i

Protein namei

  • Recommended name:
    Selenide, water dikinase (EC:
    Alternative name(s):
    Selenium donor protein
    Selenophosphate synthase

Gene namei

  • Name:selD


  • Synthesizes selenophosphate from selenide and ATP.

Sequence similaritiesi


Catalytic activityi

  • ATP + selenide + H2O = AMP + selenophosphate + phosphate.

Nucleotide bindingi

  • ATP (to residues corresponding to positions 230 - 236)

Active sitei

  • (to residues corresponding to position 17)


  • Important for catalytic activity (to residues corresponding to position 20)
