Question

Indicate your method(s) of choice for determining the structure of each of the following proteins:

1)Protein for which no information about homologs is available, but 3-D crystals can be easily obtained

2) Protein for which no information about homologs is available, and 3-D crystals are not obtained, but 2-D crystals can be easily obtained

3)Protein for which no information about homologs is available, and neither 3-D nor 2-D crystals can be obtained

4)Protein for which crystals are not obtained but a homolog from other organism with a 50% level of similarity is known

NOTE: In some cases two approaches may be equally applicable, separately or in combination; in such cases, you need to indicate both

The methods available are:

X-ray crystallography

NMR spectroscopy

Cryo-electron microscopy and electron crystallography

Homology modeling

A priori predictions
