Description and Uses
Description

Three copies of the histone gene repeat unit (each repeat contains one copy of each of His1, His2A, His2B, His3 and His4). Each copy of the His3 gene has been mutated to contain the amino acid replacement K18R and each copy of the His4 gene has been mutated to contain the amino acid replacement K8R.
