Thread: processible

I'd like to know a good translation for the word "processible" in this long sentence. It's about avian influenza pathogenicity.

In contrast, the cleavage site of HPAI viruses generally contains additional basic amino acids (arginine and /or lysine) which renders it processible for subtilysin -like endoproteases specific for a minimal consensus sequence of R-X-K-/R-R-

Thanks a lot Mariela
