Miscellaneousi

Miscellaneous

There are only 11 differences between the sequence of testosterone 15-alpha-hydroxylase and that of coumarin 7-hydroxylase. By site-directed mutagenesis it has been shown that modification of position 209 is sufficient to convert the specificity of the two forms of the enzyme.
