sub·til·i·sin

(sŭb-til'ĭ'sin),
A proteinase produced by Bacillus subtilis and other species, similar to the serine proteinases of other molds and bacteria; it catalyzes the hydrolysis of a few specific peptide bonds in certain proteins, converting chymotrypsinogen to chymotrypsin and ovalbumin to plakalbumin in this manner, and cleaves pancreatic ribonuclease into S-peptide and S-protein.
Synonym(s): subtilopeptidase

subtilisin

(sŭb-tĭl′ĭ-sĭn)
n.
Any of several extracellular enzymes produced by bacteria of the genus Bacillus that catalyze the breakdown of proteins into polypeptides and are widely used in detergents and cleaning products.

In just six weeks they had a new subtilisin that, instead of breaking down proteins, can be coaxed to do the reverse: build long chains of amino acids in DMF solvent, Arnold says.
With subtilisin, the researchers were lucky to observe a stepwise progression of the protein product toward an enzyme that could function in the hostile environment of organic solvents.
