||The structure of human oxyhaemoglobin was determined by single crystal X-ray analysis at 2.1 A resolution. Data were collected on an Arndt-Wonacott camera at -2 degrees C. The structure was refined to an R factor of 0.223 by the Jack-Levitt method, starting from Baldwin's model of human carbon monoxide haemoglobin.
||The distance of the iron from the mean plane of N(porphyrin) is 0.40(5) A and 0.36(5) A, respectively, at the alpha and beta haems, in contrast to the corresponding distance of +0.12(8) A and -0.11(8) A in oxyhaemoglobin ( Shaanan , 1983). Figures in parentheses are standard deviations of last digit.
