Why would proteases have different molecular structures

Why would proteases have different molecular structures

i guess it's cause the proteins they're breaking down have difference structures so the pro teases in turn also need varying structures suited to the particular protein

What the aspiringdoc said.

Think about it this way, you have heaps of proteins in your body so if you had a protease which had the SAME binding site (active site), that means it would be highly non-specific and thus cleave and breakdown many proteins which may be critical for life. By having many different types of proteases, you can gain more finer tuning of what proteins are cleaved and whatnot.

The answers above are absolutely correct. I think you may be mistakenly thinking that protease is an enzyme for one protein. Nah bro, protease is the general name for the enzymes that break down protein molecules, and we all know that there are plenty of different proteins, hence plenty of proteases  - their respective enzymes

Thanks!
