 Protein Biosynthesis
Proteins which are destined for intracellular function are synthesized by polysomes where as those secreted by the cell or part of the membrane are synthesized in the ER.
Proteins which are synthesized for intracellular use are synthesized on the polysomes in the cytosol, e.g.
Proteins are targeted with special sequences which determine whether they remain in the ER membrane, are secreted, or become directed to an organelle such as lysosomes or mitochondria.

 Protein biosynthesis
Protein biosynthesis (Synthesis) is the process in which cells build proteins.
The term is sometimes used to refer only to protein translation but more often it refers to a multi-step process, beginning with amino acid synthesis and transcription which are then used for translation.
Protein folding — Protein folding is the process by which a protein structure assumes its functional shape or conformation.

 Evidence for in vivo ribosome recycling, the fourth step in protein biosynthesis
Unscheduled re-initiated protein should be detected as proteins slightly larger than 3A' due to the addition of amino acids at the N-terminal end coded by codons downstream from the 2A' termination signal and extended translation into the 3A' cistron.
Second, frame shifting occurs during re-initiation; hence, the reporter protein was synthesized in the absence of RRF regardless of whether the reporter gene was in-frame (Figures 4 and 7), -2 nucleotides out-of-frame (Figure 4), or -1 nucleotide out-of-frame (Figures 6 and 7).
Unlike the bacteriostasis observed when other protein synthesis factors are inactivated, RRF inactivation is bactericidal during the transition state from the stationary to the growing phase (Figure 2).

 Botany online: Molecular Genetics - Protein Biosynthesis - Translation
The already mentioned 'factors' are proteins that are needed for the initiation, elongation and the termination of the polypeptide chain.
Part of the new proteins remains in the cytosol while others are exported through the membrane or imported into mitochondria or chloroplasts.
The expense is understandable when realising that the products (proteins, enzymes, regulators) have key functions in the cell's metabolism: the trouble-free operation of the single metabolic pathways is dependent on their function.

 Protein synthesis and engineering. Protein biosynthesis
Proteins dictate the nature and speed of chemical reactions in an organism and so control what the organism is and does.

Within the Chl-apoprotein thylakoid biosynthesis center, Chl a and b are formed via an SBP at a location accessible to all Chl-binding apoproteins.
The multiple Chl biosynthetic routes are observed, individually or in groups of one or several adjacent routes, as Chl-apoprotein thylakoid biosynthesis subcenters that are earmarked for the coordinated assembly of individual Ch-apoprotcin complexes.
Apoproteins destined to some of the biosynthesis subcenters may possess specific signals for specific Chl biosynthetic enzymes peculiar to that subcenter, such as 4-vinyl reductases, Chl a oxygenase or Chl a and Chl b synthetases.
