The sulfated glycosaminoglycans, such as keratan sulfate and chitin sulfate having 3-hydroxy free N-acetyl-beta-D-glucosaminyl residues as constituents, reacted with wheat germ agglutinin and Solanum tuberosum agglutinin by sugar-specific interaction. The glycosaminoglycans showed different inhibitory activities to the hemagglutination reaction of these lectins and keratan sulfate and its modif...

The amino acid sequence of Phaseolus aureus L. (mung-bean) cytochrome c has been determined. The molecule consists of a single polypeptide chain of 111 amino acid residues and is homologous with other mitochondrial cytochromes c. Comparison with the amino acid sequence of wheat-germ cytochrome c (Stevens, Glazer & Smith, 1967) shows 14 differences. On alignment with mammalian cytochromes c, mun...

While studying the phosphoglyceric acid mutase of wheat germ, we noted marked phosphatase activity when extensively purified mutase preparations were tested with n-3-phosphoglyceric acid and D-Z, 3diphosphoglyceric acid as substrates (1). Since we had found low phosphatase activity for these reagents in many biological materials (2), there was the possibility, previously discussed (l), that the...

Wheat germ oil was obtained by mechanical pressing using a small-scale screw press and by supercritical extraction in a pilot plant. With this last method, different pressures and temperatures were tested and the tocopherol concentration in the extract was monitored during extraction. Then supercritical extracted oil as well as commercial pressed oil were deacidified in a countercurrent column ...

Soybean flour and wheat germ are the two most important protein components of wheat germ-based insect artificial diets. The effect of modifying the proportion of these two ingredients in a Noctuidae-specific diet was investigated utilizing the tobacco budworm Heliothis virescens (F.) (Lepidoptera: Noctuidae), with the goal of developing a suboptimal diet that, without drastically affecting this...

The association of host proteins with viral RNA replication proteins has been reported for a number of (+)-strand RNA viruses. However, little is known about the identity or function of these host proteins in viral replication. In this paper we report the characterization of a host protein associated with the RNA-dependent RNA polymerase (RdRp) from brome mosaic virus (BMV)-infected barley. A h...

A protein kinase was extensively purified to near-homogeneity from wheat germ by a procedure involving affinity chromatography on casein-Sepharose 4B, gel filtration, and repeated chromatography on carboxymethyl-Sepharose CL-6B. The protein kinase preparations have the highest specific activities (up to 656 nanomoles phosphate incorporated per minute per milligram of protein) yet reported for p...

In this study, we further examined the sequence selectivity of camptothecin in mammalian topoisomerase I cDNA from human and Chinese hamster. In the absence of camptothecin, almost all the bases at the 3'-terminus of cleavage sites are T for calf thymus and wheat germ topoisomerase I. In addition, wheat germ topoisomerase I exhibits preference for C (or not T) at -3 and for T at -2 position. As...

Gobbett Lactic acid bacteria strains were identified from wheat germ by 16S rRNA partial sequencing, subjected to RAPD-PCR typing and screened. Lactobacillus plantarum LB1 and Lactobacillus rossiae LB5 were used as start...
