The biochemistry of heme biosynthesis
[作者：Heinemann, IU; Jahn, M; Jahn, D,期刊：Archives of Biochemistry and Biophysics , 页码：238-251 , 文章类型： Article，,卷期：2008年474-2]
Heme is an integral part of proteins involved in multiple electron transport chains for energy recovery found in almost all forms of life. Moreover, heme is a cofactor of enzymes including catalases, peroxidases, cyto...

Biosynthesis of vitamin B-2: Structure and mechanism of riboflavin synthase
[作者：Fischer, M; Bacher, A,期刊：Archives of Biochemistry and Biophysics , 页码：252-265 , 文章类型： Article，,卷期：2008年474-2]
The biosynthesis of one riboflavin molecule requires one molecule of GTP and two molecules of ribulose 5-phosphate as substrates. GTP is hydrolytically opened, converted into 5-amino-6-ribitylamino-2,4(1H,3H)-pyrimidi...

The methionine sulfoxide reductases: Catalysis and substrate specificities
[作者：Boschi-Muller, S; Gand, A; Branlant, G,期刊：Archives of Biochemistry and Biophysics , 页码：266-273 , 文章类型： Article，,卷期：2008年474-2]
Oxidation of Met residues in proteins leads to the formation of methionine sulfoxides (MetSO). Methionine sulfoxide reductases (Msr) are ubiquitous enzymes, which catalyze the reduction of the sulfoxide function of the o...

Enzyme mechanisms from molecular modeling and isotope effects
[作者：Dybala-Defratyka, A; Rostkowski, M; Paneth, P,期刊：Archives of Biochemistry and Biophysics , 页码：274-282 , 文章类型： Article，,卷期：2008年474-2]
The application of kinetic isotope effects and molecular modeling to characterize three enzyme-catalyzed reactions is presented; the mechanism of the chloroacid dehalogenase catalyzed reaction is approached using chlorin...

Structural and functional diversity of ferredoxin-NADP(+) reductases
[作者：Aliverti, A; Pandini, V; Pennati, A; de Rosa, M; Zanetti, G,期刊：Archives of Biochemistry and Biophysics , 页码：283-291 , 文章类型： Article，,卷期：2008年474-2]
Although all ferredoxin-NADP(+) reductases (FNRs) catalyze the same reaction, i.e. the transfer of reducing equivalents between NADP(H) and ferredoxin, they belong to two unrelated families of proteins: the plant-type an...

The growing VAO flavoprotein family
[作者：Leferink, NGH; Heuts, DPHM; Fraaije, MW; van Berkel, WJH,期刊：Archives of Biochemistry and Biophysics , 页码：292-301 , 文章类型： Article，,卷期：2008年474-2]
The VAO flavoprotein family is a rapidly growing family of oxidoreductases that favor the covalent binding of the FAD cofactor. In this review we report on the catalytic properties of some newly discovered VAO family mem...

Highlights of glucosamine-6P synthase catalysis
[作者：Durand, P; Golinelli-Pimpaneau, B; Mouilleron, S; Badet, B; Badet-Denisot, MA,期刊：Archives of Biochemistry and Biophysics , 页码：302-317 , 文章类型： Article，,卷期：2008年474-2]
L-Glutamine:D-fructose-6-phosphate amidotransferase, also known as glucosamine-6-phosphate synthase (GlcN6P synthase), which catalyzes the first step in a pathway leading to the formation of uridine 5'-diphospho-N-acetyl...

Directed evolution of aldolases for exploitation in synthetic organic chemistry
[作者：Bolt, A; Berry, A; Nelson, A,期刊：Archives of Biochemistry and Biophysics , 页码：318-330 , 文章类型： Article，,卷期：2008年474-2]
This review focuses on the directed evolution of aldolases with synthetically useful properties. Directed evolution has been used to address a number of limitations associated with the use of wild-type aldolases as catal...

Chaperonins: The hunt for the Group II mechanism
[作者：Bigotti, MG; Clarke, AR,期刊：Archives of Biochemistry and Biophysics , 页码：331-339 , 文章类型： Article，,卷期：2008年474-2]
Chaperonins are multi-subunit complexes that enhance the efficiency of protein-folding reactions by capturing protein substrates in their central cavities. They occur in all prokaryotic and eukaryotic cell types and, alo...

Enzymology in Europe and trends in enzymology 2008
[作者：Vanoni, MA,期刊：Archives of Biochemistry and Biophysics , 页码：225-225 , 文章类型： Editorial Material，,卷期：2008年474-2]

Iron-sulfur cluster biosynthesis in bacteria: Mechanisms of cluster assembly and transfer
[作者：Fontecave, M; Ollagnier-De-Choudens, S,期刊：Archives of Biochemistry and Biophysics , 页码：226-237 , 文章类型： Article，,卷期：2008年474-2]
Iron-sulfur [Fe-S] clusters are ubiquitous ancient prosthetic groups that are required to sustain fundamental life processes. Formation of intracellular [Fe-S] clusters does not occur spontaneously but requires a complex...
