The pyruvate dehydrogenase multienzyme complex
Current Opinion in Structural Biology, 1992Abstract During the review period, several structures of component enzymes and domains of enzymes of this multienzyme complex were determined. Three structures of the flavoprotein component, dihydrolipoamide dehydrogenase, became available. The structure of the core component, dihydrolipoyl acetyltransferase, can in principle be constructed from the ...

Assembly of multienzyme complexes on DNA nanostructures
Nature Protocols, 2016In nature, the catalytic efficiency of multienzyme complexes highly depends on their spatial organization. The positions and orientations of the composite enzymes are often precisely controlled to facilitate substrate transport between them. Self-assembled DNA nanostructures hold great promise for organizing biomolecules at the nanoscale.

DNA-directed assembly of artificial multienzyme complexes
Biochemical and Biophysical Research Communications, 2008This study aims to establish model systems for the exploration of proximity effects, occurring in natural multienzyme complexes. DNA-directed assembly of covalent conjugates of DNA oligonucleotides and Glucose Oxidase (GOX) or Horseradish peroxidase (HRP) was used to generate supramolecular complexes, in which the two enzymes were arranged with defined

Regulation of the Pyruvate Dehydrogenase Multienzyme Complex
Annual Review of Nutrition, 1993To maximize catalytic efficiency in metabolic pathways of both prokaryotic and eUkaryotic cells, enzymatic components are occasionally clustered or complexed physically. Organization of multiple catalytic functions into a single enzyme complex can be accomplished in two ways.

The Pyruvate Dehydrogenase Multienzyme Complex
Angewandte Chemie International Edition in English, 1975AbstractThe three enzymes pyruvate dehydrogenase, dihydrolipoamide transacetylase, and dihydrolipoamide dehydrogenase constitute the pyruvate dehydrogenase multienzyme complex of E. coli; in mammals the complex also contains a kinase and a phosphatase.

Multienzyme Complex in Fatty Acid Biosynthesis
2023Fatty acid biosynthesis is a fundamental process that occurs in all living organisms and involves multiple reaction steps. Thus, a systematic transfer of the intermediates between the different catalytic sites is highly required for the efficient regulation of a pathway as well as for sustaining growth.

A Multienzyme Bioreactor Based on a Chitinase Complex
Прикладная биохимия и микробиология, 2014A heterogeneous biocatalyst containing a complex of chitinolytic enzymes isolated from the culture medium of bacteria Clostridium paraputrificum on the surface of macroporous monolithic minidisc was obtained. The complex of chitinolytic enzymes was immobilized on the polymer matrix using a multistep method involving the introduction of an intermediate ...

Research progress and the biotechnological applications of multienzyme complex
Applied Microbiology and Biotechnology, 2021The multienzyme complex system has become a research focus in synthetic biology due to its highly efficient overall catalytic ability and has been applied to various fields. Multienzyme complexes are formed by cascading complexes, which are multiple functionally related enzymes that continuously and efficiently catalyze the production of substrates ...

[Symmetry of multienzyme complexes].
Molekuliarnaia biologiia, 1986A model for studying the symmetry of stable states arising from polyenzymic complex conformations is proposed. A formal scheme of submolecular structure self-assembly, on which the model is based, enables it not only to limit the class of conformations but in some cases to determine the structure of a complex in an unambigous manner. The model is shown

Publisher Summary This chapter discusses certain features of a few well-documented examples of multienzyme complexes. The multienzyme complexes that have been most thoroughly described are composed of two to six functionally related enzymes and have molecular weights ranging from a few hundred thousand to a few million. The particles contain definite
