Enzyme defect: A disorder resulting from a deficiency (or functional abnormality) of an enzyme. For example, newborns are routinely screened for certain enzyme defects, such as phenylketonuria (PKU) and galactosemia.nzyme defect: A disorder resulting from a deficiency (or functional abnormality) of an enzyme.

It takes Saturn 29.45 years (or 10,759 days) to orbit the Sun. Astronomers call the length of time an object takes to go around the Sun its orbital period. So the orbital period of Saturn is 29.45 years. Saturn. Image credit: Hubble. One of the interesting facts about Saturn is that its axis is tilted off the plane of the ecliptic (just like Earth).
Rotation Period and Day Length (If you are math-phobic, refer to The Use of Mathematics in My Lecture Classes) (Note added Mar 30, 2015: A newly determined rotation rate for Saturn is 10 seconds longer than the value used in the tables below, but since the new rate has an uncertainty of 45 seconds, there is no good reason to change the values shown here.)
