The general aminopeptidase PepN from Streptococcus thermophilus A was purified to protein homogeneity by hydroxyapatite, anion-exchange, and gel filtration chromatographies. The PepN enzyme was estimated to be a monomer of 95 kDa, with maximal activity on N-Lys-7-amino-4-methylcoumarin at pH 7

Centromeres are rapidly evolving across eukaryotes, despite performing a conserved function to ensure high-fidelity chromosome segregation. CENP-A chromatin is a hallmark of a functional centromere in most organisms. Due to its critical role in kinetochore architecture, the loss of CENP-A
In blood DNA extraction, Proteinase K, an enzyme commonly used to degrade proteins, can help break down the cellular and nuclear membranes, releasing DNA from the cells that protect it from degradation and increase purity/yield making it more suitable for various molecular biology techniques.
