Purification and Properties of a Novel sp . R 48 Enzyme , Trehalose Synthase , from Pimelobacter

transglucosy]ation. The enzyme also converted trehatose into ma]tose but was inactive on o-ther saccharides. The N-termina] amino acid of the enzyme was serine. The optimum pH and temperature were pH 7.5 and 200C, respective]y, The enzyme was stab]e in the range of pH 6,O-9.0 and up to 30eC for 60 min. The rate of conyeTsion of maltose ;nto trehalose was independent of the mattose concentration...

wuthering heights and the concept of marality/a sociological study of the novel

to discuss my point, i have collected quite a number of articles, anthologies, and books about "wuthering heights" applying various ideas and theories to this fantastic story. hence, i have come to believe that gadamer and jauss are rightful when they claim that "the individaul human mind is the center and origin of all meaning," 3 that reading literature is a reader-oriented activity, that it ...

Purification and properties of the enzyme chondroitinase.

The enzymatic degradation of chondroitin sulfuric acid can be catalyzed by purified bovine testicular hyaluronidase (1, 2) and by an enzyme preparation from Flavobacterium heparinum (3). Dodgson and Lloyd (4) obtained a chondroitinase from Proteus vulgaris that converted chondroitin sulfuric acid to the disaccharide, N-acetylchondrosin sulfate. Previous work from this laboratory (5) has confirm...

Purification and properties of uroporphyrinogen I synthase from human erythrocytes. Identification of stable enzyme-substrate intermediates.

Purification and Properties of the Enzyme*

An enzyme, “protein methylase I,” which methylates its endogenous protein has been purified from calf thymus. Acid hydrolysis of the methylated endogenous protein gives rise to two methylated amino acid derivatives. Both derivatives are very sensitive to alkali treatment, and one of the decomposition products is identified as methylurea. These findings, as well as other evidence, indicate that ...
