| 产品介绍 | CAS号：12650-88-3 分子量：single-chain 14.3kDa MDL：MFCD00131557 级别/活性：BR,≥40,000 units/mg protein 纯度：≥90% (HPLC) 外观/性状：lyophilized powder 酶活性定义：One unit will produce a ΔA450 of 0.001 per min at pH 6.24 at 25 °C, using a suspension of Micrococcus lysodeikticus as substrate, in a 2.6 mL reaction mixture (1 cm light path). Biochem/physiol Actions: Lysozyme hydrolyzes β(1→4) linkages between N-acetylmuramic acid and N-acetyl-D-glucosamine residues in peptidoglycan and between N-acetyl-D-glucosamine residues in chitodextrin. Gram-positive cells are quite susceptible to this hydrolysis as their cell walls have a high proportion of peptidoglycan. Gram-negative bacteria are less susceptible due to the presence of an outer membrane and a lower proportion of peptidoglycan. However, these cells may be hydrolyzed in the presence of EDTA that chelates metal ions in the outer bacterial membrane. The enzyme is active over a broad pH range (6.0 to 9.0). At pH 6.2, maximal activity is observed over a wider range of ionic strengths (0.02 to 0.100 M) than at pH 9.2 (0.01 to 0.06 M). L6876 (Sigma-Aldrich) |
