Matrix metalloproteinases: A double edge sword
Dentistry and Medical Research, 2016 Dental caries is a dynamic process which results in demineralization of inorganic constituents and destruction of organic structure of the tooth. The basic mechanism of inorganic demineralization has been studied and documented well enough.

Directed enzyme evolution: climbing fitness peaks one amino acid at a time [PDF]
, 2009 Directed evolution can generate a remarkable range of new enzyme properties. Alternate substrate specificities and reaction selectivities are readily accessible in enzymes from families that are naturally functionally diverse.

Presence and expression of hydrogenase specific C-terminal endopeptidases in cyanobacteria
BMC Microbiology, 2003 Background Hydrogenases catalyze the simplest of all chemical reactions: the reduction of protons to molecular hydrogen or vice versa. Cyanobacteria can express an uptake, a bidirectional or both NiFe-hydrogenases.

Characterisation of a putative M23-domain containing protein in Mycobacterium tuberculosis.
PLoS ONE, 2021 Mycobacterium tuberculosis, the causative agent of tuberculosis remains a global health concern, further compounded by the high rates of HIV-TB co-infection and emergence of multi- and extensive drug resistant TB, all of which have hampered efforts to ...

Activity Gel Analysis of Endopeptidases in Rose Petals
Horticultural Plant Journal, 2016 Poor resolution for the identification of endopeptidase (EP) activity in activity gel assays is a critical issue in the analysis of the postharvest physiology of rose petals. In this paper, major factors influencing EP activity gel assays were evaluated.

Identification of a novel 82 kDa proMMP-9 species associated with the surface of leukaemic cells [PDF]
, 2007 MMP-9 (matrix metalloproteinase 9) plays a critical role in tumour progression. Although the biochemical properties of the secreted form of proMMP-9 are well characterized, little is known about the function and activity of cell surface-associated proMMP-
