~~'''~~LOGGERHEAD SEA TURTLE MYOGLOBIN (CYANO-MET)~~'''~~

===LOGGERHEAD SEA TURTLE MYOGLOBIN (CYANO-MET)===

~~==Overview==~~

<!--

The ~~X-ray crystal structures of~~ the ~~aquo-met and cyano-met derivatives of~~ the ~~loggerhead sea turtle~~ (~~Caretta caretta) myoglobin have been determined~~ at 2.~~0 A resolution (R = 0~~.~~182, and 0.178, respectively~~). The results here reported, representing the first reptile globin solved by X-ray crystallography, have been analyzed in parallel with data for related monomeric hemoproteins, and indicate a strong overall structural similarity between the loggerhead sea turtle and mammalian myoglobins, reflected by the 63% amino acid identity of their primary structures. The root-mean-square deviation between the entire polypeptide backbones of loggerhead sea turtle and sperm whale myoglobins, after structure superposition, is ~~0.83 A. Upon cyanide binding to~~ the ~~protein distal site, the iron-bound water molecule present in the aquo-met form is displaced by the incoming ligand~~. ~~Cyanide is oriented towards the inner part of the heme distal site forming a Fe~~-C-~~N angle of 133 degrees.~~
