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.

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).

Achromobacter lyticus M497-1 produces three kinds of alkaline proteases (protease I, II and III) in culture medium along with the bacteriolytic enzyme (Masaki, T., Nakamura, K., Isono, M. and Soejima, M. (1978) Agric. Biol. Chem. 42, 1443--1445). Among these three

The unique specificity of Achromobacter protease I for lysine residue was investigated using synthetic and natural substrates, i.e., lysine derivatives, arginine derivatives, lysine vasopressin, substance P, ACTH and insulin. The enzyme cleaved only the -Lys-X- bonds in the above substrates.

We tested a previously described protocol for fluorescence in situ hybridization of marine bacterioplankton with horseradish peroxidase-labeled rRNA-targeted oligonucleotide probes and catalyzed reporter deposition (CARD-FISH) in plankton samples from different lakes. The fraction of Bacteria detected by CARD-FISH was significantly
