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.

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.
Other Notes
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).

The complete amino acid sequence of Achromobacter lyticus protease I (EC 3.4.21.50), which specifically hydrolyzes lysyl peptide bonds, has been established. This has been achieved by sequence analysis of the reduced and S-carboxymethylated protease and of peptides obtained by enzymatic

To investigate the site specificity of two transglutaminases (TGases), that is, the enzymes from guinea pig liver (GTGase) and Streptoverticillium (MTGase), the acyl acceptor and donor sites in alpha-lactalbumin were determined. Alpha-lactalbumin was cross-linked in the presence of dithiothreitol by
