Example 1: Specialization between lactalbumin and lysozyme C. After gene duplication 300 to 400 million years ago, an enzyme lysozyme C gave rise to a gene that currently codes for α-lactalbumin, a regulatory protein expressed only in the lactating mammary gland. Learn how to map the specialization regions that distinguish lactalbumin from lysozyme C onto protein sequence and structure. Create excel spreadsheets and specialization maps in png format.

Example 2: Specialization in lactalbumin. After gene duplication 300 to 400 million years ago, an enzyme lysozyme C gave rise to a gene that currently codes for α-lactalbumin, a regulatory protein expressed only in the lactating mammary gland. Learn how to map the specialization info onto protein sequence and structure. Create excel spreadsheets with specialization data, and specialization maps in png format.
