Abstract

A chimeric serine protease whose protease domain is composeD. of two domain halves (half-sides) with a .beta.-folded sheet structure, wherein the first domain half corresponds to the first domain half of a first serine protease and the second domain half corresponds to the second domain half of a second serine protease, has improved properties and can be readily crystallized.
