Extra cellular enzyme

In this study we examined diversity and activities of some actinomycetes isolated from mangroves in Giao Thuy, Nam Dinh Province. The distribution of actinomycetes in soil is strongly affected by external factors. Extra-cellular enzyme producing ability of mangrove actinomycetes is very high, particularly the ability of producing cellulase degrading filter paper (122/128 strains), CMC (110/128 strains), protease (83/128 strains) and amylase (78/128 strains).

Endophytic bacteria exhibit a complex web of interactions with host plants and have been extensively studied over the last several years as prolific sources of new bioactive natural products. The present study was conducted for isolation of endophytic bacterial population of Ocimum sanctum and Aloe vera and their evaluation for enzymatic activity and plant growth promotion. Morphological characteristics of the bacterial endophytes confirmed that all the bacterial isolates were either gram positive or gram negative rods and cocci.

Plasmid induces the production of extra-cellular enzymes called β-lactamases, and also, encoded resistance genes which are often located within genetic elements. This study evaluated the plasmid profile of bacterial isolates cultured from urine samples of HIV seropositive pregnant women that attended antenatal clinic of the Ondo State Specialist hospital, Akure. Plasmid analysis of bacterial isolates was also done by alkaline method. The resistance gene (plasmid) was detected in E. coli and Pseudomonas aeruginosa isolates used.

The metalloendopeptidase 24.15 (EP24.15) is ubiquitously present in the extracellular environment as a secreted protein. Outside the cell, this enzyme degrades several neuropeptides containing from 5 to 17 amino acids (e.g. gonadotropin releasing hormone, bradykinin, opioids and neuro-tensin). The constitutive secretion of EP24.15 from glioma C6 cells was demonstrated to be stimulated linearly by reduced concentrations of extra-cellular calcium.
