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.

Actions biochimiques/physiologiques

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.

Définition de l'unité

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.

Sample preparation, including bacterial lysis, remains a hurdle in the realization of complete point-of-care tests for many pathogens. Here, we developed a sample preparation methodology for enzymatic lysis and sample heating for low-resource, point-of-care applications. We show an instrument-free chemical

Enzymes are the cornerstone of modern biotechnology. Achromopeptidase (ACP) is a well-known enzyme that hydrolyzes a number of proteins, notably proteins on the surface of Gram-positive bacteria. It is therefore used for sample preparation in nucleic acid tests. However, ACP

Protocoles

Enzymatic Assay of Achromopeptidase

To measure achromopeptidase activity, this procedure uses bacterial cells and a turbidimetric rate assay. Turbidity is measured at 600 nm using a spectrophotometer.
