Amino acid synthesis [moved to microbiology thread :-) ]

Postby neon » Mon Jul 10, 2006 2:12 pm

Could somebody confirm whether my assumptions are correct please?

Micro-organisms such as e.coli can synthesise all of the amino acids required for the proteins they produce. I assume the constituents of these amino acids come from molecules they ingest from the environment.

Is this correct? If so, what mechanism is responsible for converting resources in to the amino acids? I presume it cant be a gene, as these encode for amino acids themselves. Perhaps these amino acids arise as intermediary parts of metabolic pathways?
Does this make sense or I am way off target?

thanks

Glycolysis is the main pathway..when it's converted into PGAL, then this molecule can be converted into amino acids by running the amination proceesses.

I think, moving this post into Microbiology thread would be more proper since it talked about E.coli.. :lol:

Thanks for your reply :-)
I will indeed move it to the microbiology thread.

Best wishes
