Description

Application

Achromopeptidase is useful for lysis of Gram-positive bacteria that are resistant to lysozyme. Achromopeptidase, from Sigma, has been used for the isolation and molecular characterization of skin and soft-tissue bacterial infections.

Biochem/physiol Actions

Achromopeptidase is a lysyl endopeptidase that has a molecular weight of approximately 27 kDa. It works best between pH 8.5 -9. Approximately 500-1,500 μn/ml achromopetidase can be used to lyse cells at a density of OD₆₀₀ = 0.6 over 2 hours at 37 °C.

Achromopeptidase is a lysyl endopeptidase with a MW of ~27 kDa. It is useful for lysis of Gram-positive bacteria that are resistant to lysozyme.
pH Optimum for activity: pH 8.5 - 9
Approximately 500-1,500 un/ml achromopetidase can be used to lyse cells at a density of OD₆₀₀=0.6 over 2 hours at 37 °C.

Unit Definition

One unit will lyse 0.4 μg of Micrococcus lysodeikticus per minute by turbidimetric detection at 600 nm when suspended in buffer at pH 8.0 at 37 °C.
