Protein Structures for Future Protein Engineering - Following are some of the proteins, whose structures are known and for which. cloned genes are available, so that they can be used for protein engineering:
(i) immunoglobulins,

(ii) glucose isomerases,

(iii) amylases,

(iv) p-hydroxybenzoate hydroxylase,

(v) ribulose-1, 5, bisphosphate carboxylase (ruBP), (vi) repressor proteins, and (g) restriction edonucleases.
