A7550 Sigma

Achromopeptidase from Achromobacter lyticus

lyophilized powder, Protein ~5 % by biuret, 300-600 units/mg solid



Unit Definition

One unit will produce a change in A600 of 0.001 per minute per mL at pH 8.0 at 37 °C using a suspension of Micrococcus lysodeikticus as substrate (1 cm light path).

Physical form

Crude powder containing salts and medium components

Biochem/physiol Actions

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.
