 Kendrew’s studies of the globular myoglobin structure demonstrated that:

#SCPH05 I Biotechnology
  1. “corners” between a-helical regions invariably lacked proline residue.

  2. highly polar or charged amino acid residues tended to be located interiorally.

  3. myoglobin was completely different from hemoglobin, as expected.

  4. the structure was very compact, with virtually no internal space available for water.

The phosphate transport system in bacteria imports phosphate into the cell even when the concentration of phosphate outside the cell is much lower than the cytoplasmic phosphate concentration. Phosphate import depends on a pH gradient across the membrane—more acidic outside the cell than inside the cell. In this bacterial cell, phosphate transport is an example of:
