Lyticase from Arthrobacter luteus
SIGMA/L2524 - lyophilized powder, ≥2,000 units/mg protein, Protein ≥20 % by biuret
Synonym: (1,3)-β-D-Glucan endohydrolase; 1,3-β-Glucan glucohydrolase; Bacterial lyticase; Lysing enzyme
CAS Number: 37340-57-1
MDL Number: MFCD00131560
Product Type: Chemical
Lyticase specificity: Yeast β-glucan is a polymer of β-(1-3)-D-glycopyranosyl units with branching at β-(1-6)-D-glycopyranosyl units.
Yeast cells are difficult to disrupt because the cell walls may form capsules or resistant spores. DNA can be extracted from yeast by using lysing enzymes. Lyticase is preferred to digest cell walls of yeast and generate spheroplasts from fungi for transformation. Lyticase contains β-(1→3)-glucan laminaripentaohydrolase with additional β-(1→3)-glucanase, protease, and mannanase activities.

| Biochem/physiol Actions: | Lyticase enzyme is frequently used in fungal research, particularly for species identification using polymerase chain reaction (PCR)-based techniques. It can break down β (1→3) and β (1→4) bonds between glucose units. Lysozyme serves as an indicator of macrophage-mediated host response, correlates with white cell death, and exhibits a high turnover rate. Elevated levels of serum lysozyme have been observed in various chronic inflammatory conditions, inflammatory bowel diseases, hematological disorders, and renal disorders. The c-type lysozyme from hen egg white is commonly used as a model for studying protein structure and function. Muramidase primarily exhibits bactericidal activity against Gram-positive bacteria. The method described in the bulletin for determining molecular masses using gel filtration chromatography is a modified version of existing published techniques. The protein standards included in this kit may be compatible with other chromatographic systems like high-performance liquid chromatography (HPLC). However, certain buffer systems may affect the elution volumes of albumin and carbonic anhydrase. The proteins in this kit have a molecular mass range spanning from 29 kDa to 699 kDa. |
| Biochem/physiol Actions: | Lyticase hydrolyzes poly-β(1→3)-glucose such as yeast cell wall glucan. |
| Biochem/physiol Actions: | Yeast cells are difficult to disrupt because the cell walls may form capsules or resistant spores. DNA can be extracted from yeast by using lysing enzymes such as lyticase to induce partial spheroplast formation. Spheroplasts are subsequently lysed to release DNA. Lyticase is preferred to digest the cell walls of yeast and generate spheroplasts from fungi for transformation. It contains β-(1 |
