The antitoxin Phd from the phd / doc module of bacteriophage P1 was crystallized in two distinct crystal forms. Crystals of His‐tagged Phd contain a C‐terminally truncated version of the protein and diffract to 2.20 Å resolution. Crystals of untagged Phd purified from the Phd–Doc complex diffract to 2.25 Å resolution. These crystals are partially merohedrally twinned and contain the full‐length version of the protein.
