hormone and enzyme are substances which both contain proteins, they are coded for by DNA. They both
fit together with their target by a lock and key fit, in other words their
form or shape is very important to the way they function and mutation in the
DNA can affect that shape. But hormones are informational molecules, inother
words they travel through the blood to signal distant parts of the body to do
something. Human growth hormone signals cell division and bone growth. It
only works on cells that have the proper receptor or "docking station" on
their surfaces. Enzymes are catalysts, they make chemical reactions go
faster than they normally would so metabolism can take place at a useful rate.

Not true.
Hormones are not all proteins, while it is the case for all enzyme. None of them "contain" proteins, they are proteins (when they are a cahin of amino acid) or they are not.
Only proteins are coded for by DNA.

The rest is a simplification, but mostly correct

oh, now im realize my mistake. actually, they are protein, but has some exemption for both of them. such as enzyme such as ribozyme that take part in translation is not a protein. it work in the protein free enviroment. maybe my english not so good. so thanks canalon for the correction.
