'''THE THREE-DIMENSIONAL STRUCTURE OF CAPSULE-SPECIFIC CMP:2-KETO-3-DEOXY-MANNO-OCTONIC ACID SYNTHETASE FROM ESCHERICHIA COLI'''
===THE THREE-DIMENSIONAL STRUCTURE OF CAPSULE-SPECIFIC CMP:2-KETO-3-DEOXY-MANNO-OCTONIC ACID SYNTHETASE FROM ESCHERICHIA COLI===




==Overview==
<!--  
CMP-Kdo synthetases from Gram-negative bacteria activate Kdo for incorporation into lipo- and capsule-polysaccharides. Here we report the crystal structure of the capsule-specific synthetase from E. coli at 2.3 A resolution. The enzyme is a dimer of 2 x 245 amino acid residues assuming C2 symmetry. It contains a central predominantly parallel beta-sheet with surrounding helices. The chain fold is novel; it is remotely related to a double Rossmann fold. A large pocket at the carboxyl terminal ends of the central. beta-strands most likely accommodates the catalytic center. A putative phosphate binding site at the loop between the first beta-strand and the following helix is indicated by a bound iridium hexachloride anion.
The line below this paragraph, {{ABSTRACT_PUBMED_8706906}}, adds the Publication Abstract to the page
(as it appears on PubMed at http://www.pubmed.gov), where 8706906 is the PubMed ID number.
