In this article we will discuss about the biosynthesis of various types of nucleotides:- 1. Pyrimidine Nucleotides 2. Purine Nucleotides. 1. Pyrimidine Nucleotides: Biosynthesis of pyrimidine nucleotides begins with condensation of a carbamyl residue of carbamyl phosphate with aspartic acid to produce carbamyl aspartate and inorganic phosphate. Carbamyl aspartate is dehydrated and cyclized to dihydro-orotic acid which is next dehydrogenated [...]
In this article we will discuss about the regulation and control of metabolism in microorganisms. The biological organisms, specially microorganisms take up nutrients and metabolize them through numerous enzyme-catalysed reactions to build-up their body components as well as extract energy. All these anabolic and catabolic reactions run in a highly coordinated and harmonious manner to ensure optimal growth and multiplication [...]
In this article we will discuss about the incorporation of ammonia into organic compounds. Nitrogen is an essential element for all living organisms and also viruses, coming next in importance to carbon. Nitrogen forms about 14% of the dry weight of the living matter, where it is primarily present as a constituent of proteins and nucleic acids. Although molecular nitrogen [...]
