OX NCBI_TaxID=782; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=Madrid E; RX MEDLINE=99039499; PubMed=9823893; DOI=10.1038/24094; RA Andersson S.G.E., Zomorodipour A., Andersson J.O., RA Sicheritz-Ponten T., Alsmark U.C.M., Podowski R.M., Naeslund A.K., RA Eriksson A.-S., Winkler H.H., Kurland C.G.; RT "The genome sequence of Rickettsia prowazekii and the origin of RT mitochondria."; RL Nature 396:133-140(1998). CC -!- CATALYTIC ACTIVITY: 6-[(1S,2R)-1,2-dihydroxy-3- CC triphosphooxypropyl]-7,8-dihydropterin = 6-pyruvoyl-5,6,7,8- CC tetrahydropterin + triphosphate. CC -!- COFACTOR: Binds 1 zinc ion per subunit (By similarity). CC -!- PATHWAY: Tetrahydrobiopterin biosynthesis; second step. CC -!- SUBUNIT: Homohexamer formed of two homotrimers in a head to head CC fashion (By similarity). CC -!- MISCELLANEOUS: The active site is at the interface between 2 CC subunits. The proton acceptor Cys is on one subunit, and the CC charge relay system is on the other subunit. CC -!- SIMILARITY: Belongs to the PTPS family.
