The reaction of fumarase with iodoacetate and 4-bromocrotonate.
The reaction of fumarase with several alkylating agents has been examined. The structural similarity between these compounds and the natural substrates for the enzyme, fumarate and malate, suggested that reaction might occur with structures in the active sites. Of all the compounds tested, only iodoacetate and 4-bromocrotonate inactivated fumarase by modification of structures other than the th...
متن کاملThe reaction of iodoacetate with ribonuclease-S.
The reaction of iodoacetic acid with ribonuclease has been studied recently by Gundlach et al. (1). Inactivation of the enzyme occurred over a wide range of pH. The authors concluded that at acid pH the reaction involved solely methionyl residues, that at pH 5.5 a histidyl residue was the principal site of attack, and that at alkaline pH values significant reaction at lysyl residues occurred. O...
متن کاملthe evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
15 صفحه اولThe reaction of iodoacetate with methionine.
lodoacetic acid and its amide have been widely used in protein chemistry as reagents for sulfhydryl groups. Although both can be expected to undergo other reactions with proteins, for example, with the e-amino groups of lysine residues, the imidazole groups of histidine residues, and the phenolic hydroxyls of tyrosine residues, these reactions arc generally slower than is the one with sulfhydry...
