Me even if you dont give me the answer to this question at least me understand how to get the ! the structures of the amino acids lysine and aspartic acid are shown: the tertiary structure of a given protein contains an interaction between aspartic acid and lysine. discuss the effect that replacing the lysine with another amino acid may have on the tertiary structure and function of the protein. predict which types of amino acids would cause the least amount of change to the tertiary structure of the protein and explain why.

all amino acids have two ionizable groups (an alpha-amino group with pka~9.3, and an alpha-carboxyl group with pka~2.2). lysine also has an ionizable side-chain (r) with a pka of 10.5. what percentage of the lysine side chain is deprotonated at ph 11.5? show work. 0.099% 9.1% 0.99% 90.9%

The primary amino acid sequence of the epidermal growth factor receptor (egfr) contains an invariant lysine amino acid essential for kinase activity. substitution of this essential lysine by any other amino acid blocks the capacity of the receptor to phosphorylate targets. what stage of receptor activation is disrupted by substitution of the invariant lysine with another amino acid? when this lysine is replaced by another amino acid: a) egfr is unable to activate an associated trimeric g-protein. b) the ligand epidermal growth factor (egf) is unable to bind to egfr. c) docking sites for egfr target proteins are not generated inside the cell. d) egfr becomes constitutively activated, that is, egfr is always on. e) enzymatically inactive egfr monomers are unable to dimerize.
