Serratia marcescens nuclease (, endonuclease (''Serratia marcescens''), barley nuclease, plant nuclease I, nucleate endonuclease) is an

enzyme Enzymes () are proteins that act as biological catalysts by accelerating chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products. A ...
