Insertion of a 27 amino acid viral peptide in different zones ofEscherichia coliβ-galactosidase: Effects on the enzyme activity [PDF]
FEMS Microbiology Letters, 1994 Seven internal, putatively exposed regions of Escherichia coli beta-galactosidase have been explored regarding their tolerance to insertions of large foreign peptides. Small sequence modifications, including amino acid substitutions and small deletions, were introduced into the lacZ gene to generate unique BamHI restriction sites. By using these mutant

Senescence Associated β-galactosidase Staining
Bio-Protocol, 2012 Detection of senescent cells using a cytochemical assay was first described in 1995 (Dimri et al., 1995). The identification of senescent cells is based on an increased level of lysosomal β-galactosidase activity (Kurz et al., 2000).

Tetrahedron, 2013 Synthesis of N-acetyl-D-lactosamine (Gal-β[1→4]GlcNAc, LacNAc) catalyzed by β-galactosidase from Thermus thermophilus (TTP0042) is affected by side reactions that give as result very low yields (about 20%) of LAcNAc when the reaction is performed in buffer.

Study of muscle cell dedifferentiation after skeletal muscle injury of mice with a Cre-Lox system. [PDF]
PLoS ONE, 2011 Dedifferentiation of muscle cells in the tissue of mammals has yet to be observed. One of the challenges facing the study of skeletal muscle cell dedifferentiation is the availability of a reliable model that can confidentially distinguish differentiated

International Journal of Advanced ResearchGalactosidaseis an industrially important enzymewitha number of applications in dairy, fermentation, and food industries. The study was carried out to extract and characterize the galactosidase enzymefromZiziphusspina-christi,a therapeutic herb. The enzyme was studied for pH, temperature sensitivity, and heavy metal effects on enzyme activity.

Overview of molecular signatures of senescence and associated resources: pros and cons
FEBS Open Bio, EarlyView.Cells can enter a stress response state termed cellular senescence that is involved in various diseases and aging. Detecting these cells is challenging due to the lack of universal biomarkers. This review presents the current state of senescence identification, from biomarkers to molecular signatures, compares tools and approaches, and highlights ...
