WebApr 10, 2024 · In ACD11, phenylalanine residues analogous to F50 and F52 on helix α2 of CPTP serve as “portal gates” that swing open to allow C1P entry into it’s hydrophobic cavity . Our results suggest that swinging open of these “portal gates” not only allows for C1P entry but, in fact, facilitates it by disrupting C1P’s local hydrophobic ... WebThey are basic because their side chain is basic and are positively charged at pH values below their pKa’s. Only the guanidine group (HNC (NH2)2) in Arg (pKa = 12.5) and amine group in Lys (pKa = 10.5) will accept a proton and exist with an overall charge of +1 at physiological pH.
