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).
But for Saturn, the two axes are nearly identical, so scientists have had to rely on even less direct measures to calculate its rotation rate. Using radio emissions data collected by the Voyager spacecraft in the 1980s, scientists initially determined a Saturnian day to be 10 hours, 39 minutes and 22 seconds.
