Examine the protein sequence of the small protein rbet1 belo

Examine the protein sequence of the small protein rbet1 below. rebet1 is believed to interact with another protein, membrin, via a coiled coil.

Solution

1. Coiled coils usually contain a repeated pattern of hydrophobic and charged amino acids.In this sequence the suited peptide is ACEEENDRL which is enriched with hydrophobic and charged amino acid.

2. This protein sequence indicating that this protein is cytosolic protein because sequence is enriched with charge and polar amino acids which is indicating this protein can not be a integral membrane protein.

3. The amino acid chain lenth of this protein is 118 amino acid. The average size of one amino acid is 110 dalton.

The total size will be = 118*110 = 12,980 Dalton
