TI  - Structure of SAICAR synthase from Thermotoga maritima at 2.2 angstroms reveals an
      unusual covalent dimer.
PG  - 335-9
AB  - As a part of a structural genomics program, the 2.2 angstroms resolution crystal 
      structure of the PurC gene product from Thermotoga maritima has been solved. This
      26.2 kDa protein belongs to the phophoribosylaminoimidazole-succinocarboxamide or
      SAICAR synthase family of enzymes, the members of which are involved in de novo
      purine biosynthesis. SAICAR synthase can be divided into three subdomains: two
      alpha+beta regions exhibiting structural homology with ATP-binding proteins and a
      carboxy-terminal subdomain of two alpha-helices. The asymmetric unit contains two
      copies of the protein which are covalently linked by a disulfide bond between
      Cys126(A) and Cys126(B). This 230-amino-acid protein exhibits high structural
      homology with SAICAR synthase from baker's yeast. The protein structure is
      described and compared with that of the ATP-SAICAR synthase complex from yeast.
