Question

What chemical properties do K200, and R322 have in common?

Hydropathy plot and deduced transmembrane domains of KAT1 (A) and deduced amino acid sequence (8). Hydrophobicity plot was generated by the method of Hopp and Woods with a window of 13 amino acids (6, 52). Negative values show hydrophobic regions. The positions of fusion sites selected for PhoA fusion are indicated by the bars (A) and arrowheads (B). Shows the amino acids that were replaced with valines (Materials and Methods). Represents the positively charged amino acids in the putative S4 segment. The putative transmembrane segments (S1, S2, S3, S4, S5, H5, S6, and S7) are indicated by horizontal bars. The horizontal dotted line represents the putative nucleotide-binding domain (NBD).

Explanation / Answer

Physical and Chemical properties describe the characteristics of a substance.
However, a physical change is one that simply undergoes a change of state i.e. freezing of liquid water to ice. A chemical change is observed when a substance undergoes a change in composition such as in the rusting of iron.
