[[http://www.uniprot.org/uniprot/PRZN_SERMA PRZN_SERMA]] Has insecticidal activity against the locust M.palpalis. When administered orally to locusts at a low dose it causes them to lie on their sides exhibiting sporadic limb movements and muscular twitching, followed by full recovery. When administered at higher doses the same symptoms are observed, followed by death.

== Publication Abstract from PubMed ==

The crystal structure of the 50 kDa metalloprotease from the Gram-negative bacterium Serratia marcescens has been solved and refined to a crystallographic R-factor of 0.192 at 1.80 A resolution. The structure is very similar to that of alkaline protease from Pseudomonas aeruginosa, in particular the calcium binding "parallel beta roll" motif is completely conserved. The N-terminal proteolytic domain shows the typical "metzincin" fold. The active sites of the two enzymes are slightly different, Tyr216 is a Zn ligand in the Serratia metallo protease. The loops 70-77 and 122-132, which encompass the active site cleft, differ due to insertions and deletions so that the Serratia metallo protease seems to have a more open site than the alkaline protease.
