Definition of PSSH

Curated proteins or TIGRFams with EC 2.5.1.65
Ignore hits to P9WP53 when looking for 'other' hits ([CysO sulfur-carrier protein]-thiocarboxylate-dependent cysteine synthase (EC 2.5.1.113); O-phosphoserine sulfhydrylase (EC 2.5.1.65). O-phosphoserine sulfhydrylase; OPS sulfhydrylase; CysO-thiocarboxylate-dependent cysteine synthase; Cysteine synthase B; CSase B; O-phosphoserine-specific cysteine synthase; [CysO sulfur-carrier protein]-thiocarboxylate-dependent cysteine synthase; EC 2.5.1.113. CysO-thiocarboxylate-dependent cysteine synthase monomer (EC 2.5.1.113))
Ignore hits to A2GMG5 when looking for 'other' hits (cysteine synthase (EC 2.5.1.47))
Comment: BRENDA misannotates Mt_cysM (P9WP53) as this. Trichomonas cysteine synthase (A2GMG5) probably has this activity as well, so similarity to it is ignored.

Fetched 4 sequences

Running ublast to find other characterized proteins with 40% identity and 70% coverage

Found hits to 44 other characterized sequences. (Found 48 hits including self hits.)

Removing ignored items reduces this to 42 close sequences.
