Prochymosin is one of the most important aspartic proteinases used as a milk-clotting enzyme in cheese production. In the present investigation we report sequence of cDNA encoding goat ( Capra hircus ) preprochymosin and compare its nucleotide and deduced amino acid sequences with sequences of other ruminants preprochymosin. As bovine prochymosin, the caprine prochymosin cDNA encodes 365 amino ...

Although soybean aphid (Aphis glycines) resistance is commercially available in the form of the Rag1 gene, the mechanism of this resistance is not fully understood. Amino acids are a limiting factor for aphid growth, and there is evidence that plant amino acid composition is related to aphid resistance. Antibiotic resistance like that conferred by Rag1 could be associated in part with both prot...

due to the importance of production and propagation of virus-free potato plants, some of the factors involved in the propagation of potato (plantlet production and virus-free in vitro microtuberization) has been studied. in most reports, adding a mixture of amino acids play an important role in plant tissue culture and development of the explants in many cases increase. this experiment was cond...

The concentration of 21 individual free amino acids in serum, liver, and skeletal muscle was determined in rats during the incubation, acute illness, and terminal stages of experimental infection with Diplococcus pneumoniae. By 4 hr after subcutaneous inoculation with bacteria, the concentration of total and many individual free amino acids in serum, liver, and muscle was significantly decrease...

prochymosin is one of the most important aspartic proteinases used as a milk-clotting enzyme in cheese production. in the present investigation we report sequence of cdna encoding goat ( capra hircus ) preprochymosin and compare its nucleotide and deduced amino acid sequences with sequences of other ruminants preprochymosin. as bovine prochymosin, the caprine prochymosin cdna encodes 365 amino ...

A number of studies including those of Cornish and Block (1960) have measured the marked increase in serum enzyme levels following acute exposure to CC4 vapor. If it is assumed that these enzymes are being released from damaged tissue, one would anticipate that smaller molecular weight compounds, such as amino acids, would also be released. Increased urinary excretion of free amino acids or alt...

improve forage quantity and quality using organic and biological fertilizers production of important needs in dryland farming systems of the country. in this study the effects of foliar application of four different combinations of amino acid four different time steps were germinated plant growth, stem elongation, flowering and spraying all three steps above with the control treatment was carri...

A previous investigation (Halvorson and Spiegelman, 1952) demonstrated that analogues of amino acids which prevent incorporation from the free amino acid pool into protein also suppress the induced synthesis of maltase in yeast cells. The data obtained led to the conclusion that the quantitatively predominant pathway of induced enzyme formation in nongrowing cells involves the utilization of th...
