An alkali metal aluminosilicate of the zeolite P type is manufactured by continuous mixing of a sodium silicate solution and a sodium aluminate solution in a first reaction zone in the presence of zeolite P seeds, continuously transferring this mixture to a second reaction zone, and filtering, washing, and drying the resulting product. The aluminosilicates are of value as components in detergent...
The term 'RNA editing' was used for the first time in 1986 to describe the process of uridylate insertion into trypanosomal mitochondrial transcripts. Since then, the term has been used more generally to describe a large variety of processes involving base insertions, deletions and conversions that generate RNAs with a primary sequence different to those encoded by the gene. RNA editing has been...
Alkali metal aluminosilicates of the zeolite P-type having the composition M 2n O Al 2 O 3 (1.80-2.66)SiO 2 y H 2 O (M = n-valent cation such as Na or K) rapidly remove Ca ions from water at 5°C and are useful in detergents for laundering in cold water.
C to U transitions in plant mitochondrial mRNA (RNA editing) lead to amino acid changes as well as to the creation of new initiation or termination codons. We established an in vitro system to assay and to dissect the process of wheat mitochondrial mRNA editing. A deamination mechanism explains most easily the observed C to U transitions. Several fractions of organellar protein participate in the...
