It is the first step in creating proteins.
During initiation phase of protein synthesis , most important thing formed is initiation complex .
AUG
Ribosomes play important role in the protein synthesis.
The three stages in protein synthesis are initiation, elongation, and termination. In initiation, the ribosome assembles on the mRNA and finds the start codon. During elongation, amino acids are added to the growing polypeptide chain. Termination occurs when a stop codon is reached, signaling the end of protein synthesis.
Initiation of protein synthesis is called translation initiation. This topic of research is very active and animmense amount ofwork is currently being conducted to understand the details of this process in both prokaryotes and eukaryotes.To get a better picture of the work that is going on, please refer to the attached linkhttp://www.ncbi.nlm.nih.gov/sites/entrez
A sigma factor (σ factor) is a protein needed only for initiation of RNA synthesis.
In prokaryotes, most of the control of protein synthesis occurs at the level of transcription initiation. This is achieved through the regulation of RNA polymerase activity, binding of transcription factors, and modulation of promoter sequences. Ribosomes then translate the mRNA into proteins following transcription.

Samuel D. Bernal has written: 'The mechanism of initiation of protein synthesis in E. coli'
A protein is being assembled during the translation process of protein synthesis. This occurs in the ribosomes of a cell, where transfer RNA (tRNA) molecules bring amino acids to be linked together according to the mRNA template. The process involves initiation, elongation, and termination steps to ensure the accurate construction of the protein.
The process of AUG codon recognition helps to start protein synthesis by signaling the ribosome to begin translating the genetic code into a protein. The AUG codon serves as the start codon, indicating where translation should begin. When the ribosome recognizes the AUG codon, it recruits the necessary components to initiate protein synthesis.
Linezolid works by inhibiting bacterial protein synthesis. It binds to the bacterial 23S ribosomal RNA of the 50S subunit, preventing the formation of the initiation complex and inhibiting the formation of a functional 70S initiation complex, thus blocking bacterial protein synthesis. This mechanism of action makes linezolid effective against a wide range of Gram-positive bacteria.
