sentences:  These studies have mostly been performed by biologically synthesizing batroxobin from "Bothrops moojeni" cDNA, and analyzing this product and using homology models based on other proteases, such as thrombin and trypsin, among others.One of the earlier studies from 1986 showed that the molecular weight is 25.503 kDa, 32.312 kDa with the carbohydrate, and it consists of 231 amino acids.The amino acid sequence exhibited significant homology with other known mammalian serine proteases, such as trypsin, thrombin, and most notably pancreatic kallikrein.
