| degradation of amyloid proteins with protease i from aspergillus oryzae. in vivo increase in saa clearance rate after enzyme infusion. | the effect of the thrombolytic enzyme protease i from aspergillus oryzae (brinase) on the amyloid protein aa was investigated. the effect of the enzyme on purified, low molecular weight protein aa was very high. protein aa in intact amyloid fibrils suspended in neutral buffer was also degraded by the enzyme, although at a much lower rate. amyloid fibrils in tissue sections could also be attacked and removed, leaving the tissue structure fairly intact. the in vivo effect of brinase on protein saa ... | 1982 | 6760382 |
| aminoacylase from aspergillus oryzae. comparison with the pig kidney enzyme. | aminoacylase (ec 3.5.1.14) from aspergillus oryzae was purified from a commercially available crude material by heat treatment, precipitation by polyethyleneimine and ammoniumsulfate, gel chromatography and preparative disc-gel-electrophoresis. the purified product was homogenous as judged by polyacrylamide gel electrophoresis. sds-gel electrophoresis, polyacrylamide-gel-gradient electrohoresis, gel chromatography and amino acid analysis demonstrated the enzyme to be composed of two subunits wit ... | 1980 | 6774495 |
| reversal of fungitoxicity of 8-quinolinols and their copper(ii) bischelates. ii. reversal of the action of 8-quinolinol by dl-alpha-lipoic acid. | the effect of amino acids and derivatives, krebs cycle acids and related compounds, fatty acids, and vitamins and related compounds on the toxicity of 8-quinolinol and bis(8-quinolinolato)copper(ii) to aspergillus oryzae (atcc 1011) was studied. only aliphatic thiol-containing compounds (cysteine, glutathione, dithioerythritol, and dithiothreitol) and dl-alpha-lipoic acid protected against 8-quinolinol but not its copper(ii) bischelate. it is suggested that 8-quinolinol inhibits lipoic acid bios ... | 1981 | 6790147 |
| mutagenesis during transformation of bacillus subtilis. i. an increase in "selfing' resulting from hybrid donor dnas. | reverse mutations increase when competent bacillus subtilis cells are transformed with high concentrations of homologous "selfer' dna. a high proportion of the mutants were also transformants of linked genes. a stimulation in the appearance of reversed mutations occurred when homoduplex and heteroduplex "selfer' dnas were used as donors. digestions of native and hybrid dnas with nuclease s1 from aspergillus oryzae resulted in the preferential decrease of mutations as compared to a much smaller i ... | 1981 | 6799809 |

| effects of fibrinogen fragment and proteolytic enzyme on the immune system in mice. | the immunomodulating ability of fibrinogen fragment (hol-dsk) and proteolytic enzyme with fibrinolytic activity from aspergillus oryzae was analysed in cba/ca, c57bl, c3h/hej and nmri mice. suppressive effects on the blastogenic response to mitogens were noted. no consistent suppressive effect, but sometimes an enhancing one, was recorded on the antibody responses to protein antigens. administration of hol-dsk or proteolytic enzyme shortly after the immunization resulted in a slight inhibition o ... | 1983 | 6848480 |
