Bacterial species, which are able to fix CO 2 + H 2 as only carbon and energy source to acetyl-CoA and further to acetate, are called acetogens. The pathway acetogenic bacteria possess is the linear, two-branched reductive acetyl-CoA pathway (Wood-Ljungdahl pathway), which they not only...

Gas-fermenting acetogens can upgrade one-carbon (C1) compounds (such as CO2 and CO) to the two-carbon (C2) metabolite acetyl coenzyme A (CoA) and convert sugar feedstocks to acetyl-CoA with minimal CO2 emissions. Fulfilling the biosynthetic potential of these microbes requires overcoming challeng...
This chapter discusses the synthesis of O-Acetylhomoserine. Homoserine is acetylated with acetic anhydride in a strongly acidic medium that prevents N-acetylation. Homoserine lactone is formed as a side product, which is readily separated. The general method was described some years ago and applied ...
Problems concerning the origin of acetyl groups of acetylcholine (ACh) in the brain have been reviewed recently (19,27). It is the prevailing view that the acetylcoenzyme A (acetylCoA) used for the synthesis of ACh in the brain is derived from pyruvate 12,16,28,29) and is formed by ...

The synthesis of acetyl-CoA by Clostridium thermoaceticum from carbon dioxide, hydrogen, coenzyme A and methyltetrahydrofolate It has been demonstrated that enzymes from Clostridium thermoaceticum catalyze the following reaction in which Fd is ferredoxin and CH3THF is methyltetrahy...

Yeast fatty acid synthetase catalyzes the synthesis of palmityl-CoA and stearyl-CoA from acetyl-CoA and malonyl-CoA. Acetyl-CoA serves as "primer" of the reaction cycle. The specificity of the fatty acid synthetase with respect to the "priming" substrate was studied on the purified enzyme.1In...

All plant cells produce fatty acids from acetyl-CoA by a common pathway localized in plastids. Although the biochemistry of this pathway is now well understood, much less is known about how plants control the very different amounts and types of lipids produced in different tissues. Thus, a cen...
