The R1 amino acid next to the peptide bond being hydrolyzed is selected for in the......of the serine protease. ....... has a small one and thus is selective for Gly, Ala, and Val; .....has a slitlike one that is hydrophobic and is selective for Phe, Trp, and Tyr; and ....... prefers R1 groups of Arg and Lys due to its Asp189 found at the bottom.
Homework Answers
Answer:- the R1 amino acid next to the peptide bond being hydrolyzed is selected for in the Active site of the serine proteas. Elatase-like has small one and thus is selective for gly, ala and val: Chymotrypsine-like has slitlike one that is hydrophobic and is selective for phe, trp and tyr and Trypsine-like prefers r1 groups of arg and lys due to its asp 189 found at the botttom.
