단위 정의
1 U corresponds to the amount of enzyme which increases the absorbance at 280 nm by 0.001 per minute at pH 2.0 and 37°C (Hemoglobin, Cat.No. 51290, as substrate) 15′000 absorbance-U as described above are equivalent to ∼1 Bergmeyer-U. 1 Bergmeyer-U is the amount of enzyme which hydrolyzes 1 μmol Acetyl-L-phenyl-3,5-diiodo-L-tyrosine at pH 2.0 and 37°C
분석 메모
Optimum pH is 2-4. Active in 4 M urea and 3 M guanidine HCl. Stable at 60 °C. Pepsin is irreversibly inactivated at pH 8.0 - 8.5.

Our previous report showed that yam dioscorin and its peptic hydrolysates exhibit radical scavenging activities; however, the functions of these peptic hydrolases are still under investigation. In this study, the thiol-containing peptides derived from computer-aided simulation of pepsin hydrolysis of

The African trypanosome Trypanosoma brucei, which persists within the bloodstream of the mammalian host, has evolved potent mechanisms for immune evasion. Specifically, antigenic variation of the variant-specific surface glycoprotein (VSG) and a highly active endocytosis and recycling of the surface

The only well-understood mechanism of zymogen activation is that of the serine proteinases, in which proteolytic cleavage leads to conformational changes resulting in a functional active site. A different mechanism is now unveiled by the crystal structure of pepsinogen. Salt
