Optimal assay conditions are described for 8 hydrolases of Euglena gracilis var. bacillaris, SM-L1 (streptomycin-bleached) strain, 7 of which have an acid pH-optimum. Acid-phosphatase, beta-galactosidase, beta-glucosidase, b-fucosidase, cathepsin D, RNase, DNase, and an esterase are active in cell homogenates. Amylase has very low activity, and beta-glucuronidase, arylsulfatase, beta, N-acetyl-glucosaminidase, alpha-fucosidase, and alpha- and beta-mannosidase are inactive.

The exudates or liquid droplets on various structures of a number of fungi were examined. The droplets were enveloped in membranous material and were associated with actively growing mycelia, including fruiting structures. Osmium tetroxide vapour-fixed droplets of Claviceps purpurea, Myrothecium roridum, Sclerotinia sclerotiorum, Sclerotium rolfsii, and Thanathephorus cucumeris did not dry to a powder but remained intact as spheres when freeze-dried. Fractured spheres, examined with the scanning electron microscope, showed the presence of a membranous structure similar to that of rapidly frozen colloidal solutions with the ice crystals removed by sublimation. Locules or cavities within the freeze-dried droplets are thought to be due to the entrapment of air when droplets coalesce. Biochemical analyses of the exudates showed that acid phosphatase, beta-glucosidase, acid and alkaline protease. RNase polygalacturonase and cellulase enzymes as well as oxalic acid and ammonia were present.

An enzymatic profile of 20 strains of Pseudomonas maltophilia was undertaken with conventional plate tests, API ZYM, and 4-methylumbelliferyl-conjugated substrates. All strains produced DNase, RNase, arbutinase, esterases and lipases, mucinase, acid and alkaline phosphatases, alkaline pyrophosphate diesterase, phosphoamidase, beta-glucosidase, leucine arylamidase, and acetatase and were hemolytic for horse, sheep, and rabbit blood. The majority of strains produced chitinase, hyaluronidase, albuminase, valine arylamidase, trypsin, alpha- and beta-glucosidases, and N-acetyl-beta-glucosaminidase. API ZYM and 4-methylumbelliferyl-conjugated substrate assays are rapid, simple, specific, and sensitive and may be useful as diagnostic aids in the identification of P. maltophilia and other pseudomonads.

We studied the mechanism of growth-stimulating effect of various compounds using an exogenous RNase-micromycete model and found that the treatment with microdoses of RNase intensified the reproduction of the yeast Candida valida and growth of Aspergillus fumigatus. At the same time the respiration activity of yeast cells and fungal mitochondria as well as succinate dehydrogenase activity increased. The secretion of total protein, cellulase and cellobiase changed in the presence of RNase in the growth medium. Electrophoretic mobility of Candida valida cells enhanced by 20%. The RNase stimulating effect on microbial cells seems to result from changes in characteristics of the cell surface.

Membranes were prepared from tissues of the carp Ctenopharynogodon idellus including liver, kidney, intestine, adipose tissue, ovary, gill, heart, muscle and spleen. The carp liver and intestine membranes bound 125I-labeled bovine growth hormone and the binding could be displaced by cold bovine growth hormone. No changes in the ability to bind 125I-labeled bovine growth hormone occurred after treatment of the carp liver membrane with DNase, RNase, alpha-amylase and beta-glucosidase, suggesting that neither nucleic acids nor carbohydrates played an important part in the hepatic binding of growth hormone. Treatment of carp liver membranes with either chymotrypsin or trypsin produced a decrease in the growth hormone binding activity, indicating that the growth hormone receptor on carp liver membrane is a protein. Treatment of carp liver membranes with p-chloromercuribenzoate brought about a reduction in 125I-bGH binding. The inhibition could be reversed by dithioerythritol, suggesting the involvement of essential sulfhydryl group in bGH binding.

Protein bodies and spherosomes isolated from mature seeds of Sorghum bicolor (Linn.) Moench have measurable activity of acid protease, alpha-glucosidase, beta-glucosidase, beta-galactosidase, phytase, acid pyrophosphatase, p-nitrophenyl phosphatase, and RNase. Protein bodies have largely insoluble activities, and produce soluble protein and soluble amino nitrogen during autolysis. They have the dual function of protein storage and protein catabolism. Spherosomes have considerable amounts of soluble enzymes and autolytically produce soluble amino nitrogen and inorganic phosphate but release little soluble protein. Spherosomes are similar to animal lysosomes but have an additional storage function for protein, phosphorus, and metals. Mature sorghum seed contains the necessary enzymes and substrates to generate two basic metabolites, amino acids and inorganic phosphate.
