I believe it is a "Key in a lock" formation
structural proteins and enzymes.
Diarthroses

No, it most be carefully note that all enzymes are mostly proteins and not all proteins are enzymes. Enzymes carry out the catalysis of biochemical reactions in and out of the cells. there are different non enzymatic structural and functional proteins they do have important roles such as hormones, structural proteins such as collagen etc.
Enzymes are proteins, each with a uniquely specific Biochemical Function.
Evolutionary Relationship
No, there are structural proteins, functional proteins [enzymes] and regulatory proteins. Are all enzymes proteins? Yes. Further, many proteins are closely associated with Rnas.
proteins are structural materials, energy sources, and chemical messengers.
