Arogenate (pretyrosine) is an obligatory intermediate of L-tyrosine biosynthesis: confirmation in a microbial mutant.
Wild-type Brevibacterium flavum has been shown to possess arogenate dehydrogenase activity and to lack prephenate dehydrogenase, thereby providing presumptive evidence that arogenate (previously named "pretyrosine") is an obligatory intermediate of L-tyrosine biosynthesis. A similar enzymological pattern has been discerned in extracts made from wild-type cultures of various species of cyanobact...
متن کاملIs nicotinamide adenine dinucleotide phosphate an obligatory intermediate in photosynthesis?
The site of action of the inhibitors disalicylidenepropanediamine and pyrophosphate was more closely defined as acting on ferredoxin. Three inhibitors which act on the electron transport path between ferredoxin and NADP: disalicylidenepropanediamine, pyrophosphate, and phosphoadenosinediphosphate ribose, had no effect on photosynthesis in cell free preparations of Dunaliela parva at concentrati...
متن کامل3-Hydroxy-4-methylkynurenine as an intermediate in actinomycin biosynthesis.
tryptophan1.2). The formation of 3-hydroxy-4-methylanthranilic acid probably involves a diversion of the well-known metabolic pathway leading to the formation of 3-hydroxyanthranilic acid from L-tryptophan2). However, the mechanismof transmethylation of the aromatic ring has not been examined to the extent of determining which of the alternative compounds mentioned in Fig. 1 is the pentultimate...
متن کاملThe reaction sequence in ergothioneine biosynthesis: hercynine as an intermediate.
Ergothioneine can be synthesized by the mold, Neurospora crassa, from the amino acids, histidine, methionine, and cysteine (1). The intact histidine molecule is used in the synthesis, and the three methyl groups of the betaine moiety can be derived from methionine by a triple transmethylation process (2). Cysteine appears to be an immediate precursor of the sulfur atom of the thiolimidazole rin...
متن کاملPhosphoribosyladenosine Monophosphate, an Intermediate in Histidine Biosynthesis.
The first reaction of histidine biosynthesis, the conversion of 5-phosphoribosyl-1-pyrophosphate and adenosine triphosphate to N-1-(5’-phosphoribosyl)-ATP has been described previously (1, 2). The present report describes the preparation, isolation, and characterization of N-1-(5’-phosphoribosyl)-AMP, the second intermediate in the pathway (Fig. 1). This compound is formed from phosphoribosyl-A...
