Figure 3. Classification of homologous cement proteins by amino acid composition.

Figure 3

(a) Corresponding values of hydropathy ranging from hydrophobic to hydrophilic, (b) Aliphatic index values of cement proteins are bimodal, when relative volumes of alanine, valine, isoleucine and leucine side chains are compared. (c) Left, polar GSrCPs defined by an abundance of glycine, alanine, serine and threonine residues. Right, aliphatic LrCPs defined by an abundance of valine, isoleucine and leucine residues and higher aliphatic index values. Bottom right, acid hydrolysis of whole cement from microspheres yields an abundance of glycine, alanine, serine and threonine in addition to hydrophobic residues. Asterisks indicate residues that are abundant in individual components.
