'''SOLUTION STRUCTURE OF CYTOCHROME C-552, NMR, 20 STRUCTURES'''<br />


==Overview==
==SOLUTION STRUCTURE OF CYTOCHROME C-552, NMR, 20 STRUCTURES==
The solution structure of a thermostable cytochrome c-552 from a, thermophilic hydrogen oxidizing bacterium Hydrogenobacter thermophilus was, determined by proton nuclear magnetic resonance spectroscopy. Twenty, structures were calculated by the X-PLOR program on the basis of 902, interproton distances, 21 hydrogen bonds, and 13 torsion angle, constraints. The pairwise average root-mean-square deviation for the main, chain heavy atoms was 0.91 +/- 0.11 A. The main chain folding of the, cytochrome c-552 was almost the same as that of Pseudomonas aeruginosa, cytochrome c-551 that has 59% sequence identity to the cytochrome c-552, but is less thermostable. We found several differences in local structures, between the cytochromes c-552 and c-551. In the cytochrome c-552, aromatic-amino interactions were uniquely formed between Arg 35 and Tyr 32, and/or Tyr 41, the latter also having hydrophobic contacts with the side, chains of Tyr 32, Ala 38, and Leu 42. Small hydrophobic cores were more, tightly packed in the cytochrome c-552 because of the occupancies of Ala, 5, Met 11, and Ile 76, each substituted by Phe 7, Val 13, and Val 78, respectively, in the cytochrome c-551. Some of these structural, differences may contribute to the higher thermostability of the cytochrome, c-552.

== Publication Abstract from PubMed ==
The solution structure of a thermostable cytochrome c-552 from a thermophilic hydrogen oxidizing bacterium Hydrogenobacter thermophilus was determined by proton nuclear magnetic resonance spectroscopy. Twenty structures were calculated by the X-PLOR program on the basis of 902 interproton distances, 21 hydrogen bonds, and 13 torsion angle constraints. The pairwise average root-mean-square deviation for the main chain heavy atoms was 0.91 +/- 0.11 A. The main chain folding of the cytochrome c-552 was almost the same as that of Pseudomonas aeruginosa cytochrome c-551 that has 59% sequence identity to the cytochrome c-552 but is less thermostable. We found several differences in local structures between the cytochromes c-552 and c-551. In the cytochrome c-552, aromatic-amino interactions were uniquely formed between Arg 35 and Tyr 32 and/or Tyr 41, the latter also having hydrophobic contacts with the side chains of Tyr 32, Ala 38, and Leu 42. Small hydrophobic cores were more tightly packed in the cytochrome c-552 because of the occupancies of Ala 5, Met 11, and Ile 76, each substituted by Phe 7, Val 13, and Val 78, respectively, in the cytochrome c-551. Some of these structural differences may contribute to the higher thermostability of the cytochrome c-552.
