In the human promyelocytic cell line HL60, we observed both a strong procoagulant activity (PCA) on the cell membrane and proteolytic activity in the lysate of these cells. Because these cell-line cells are susceptible to differentiation to either a more mature granulocytic or monocytic form, we were able to study the hypothesis that the combination of PCA and proteolytic activity is confined t...

Xylotrophic fungi are well known by their ability to excrete enzymes into environment. These have important biotechnological potential and some of them produce industrial enzymes. Besides, xylotrophic fungal species recently attracted a lot attention among researchers as source antibacterial drugs. Aim. To analyze the effect carbon in culture medium, conditions deep cultivation on mycelium yiel...

The proteolytic activity of gastric mucosa markedly increased from 2 to 4 wk of age in rats and from birth to 8 wk in pigs. In calves it was at adult level at birth, then decreased until d 14 and remained at a relatively low level up to d 56 of age. Early postnatal glucocorticoid injections increased (P less than .05) the proteolytic activity of gastric mucosa in rats, decreased (P less than .0...

The association between the presence of self-splicing intron Ca.LSU and proteolytic activity of Candida albicans isolates was tested. Study included 95 C. albicans strains isolated from gastrointestinal tract of diabetes children. The strains with the intron (genotype B) displayed a significantly higher proteolytic activity (385.2+/-192U/L) than did strains without intron (genotype A) (119+/-11...

The proteolytic activity of Pseudomonas fluorescens 07A was investigated, and was optimal on tryptone-calcium medium. N-acyl-homoserine lactones (AHLs) were not detected on supernatants of late-exponential and stationary-phase culture broths. Synthetic AHLs or bacterial cell extracts added to the medium did not influence growth or proteolytic activity suggesting that quorum sensing might not re...
