What is "KK1 enzyme"?

In the book "The Kaizen Way" by Robert Maurer, I’ve read the following:

When we’re sitting, our muscles go into a form of hibernation, causing
our bodies to shut down the enzyme (called KK1) that breaks down some
of the fat in the blood.

However, when I tried to google "KK1 enzyme", I got nothing about any enzyme. I mean, I got this website and this article, but they don’t contain the name "KK1" at all.

What was meant by that? Is it scientifically accurate?
