Leaky Scanning

Leaky Scanning

During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA. Marilyn Kozak discovered that the sequence RCCAUGG (where R...

From DNA to Protein

From DNA to Protein

The flow of genetic information in cells from DNA to mRNA to protein is described by the central dogma, which states that genes specify the sequence of mRNAs, which in turn specify the sequence of amino acids making up all proteins. The decoding of one molecule to another is performed by specific proteins and RNAs. Because the information stored in DNA is so central to cellular function, it makes intuitive sense that the cell would make mRNA copies of this information for protein synthesis...

Improving Translational Accuracy

Improving Translational Accuracy

Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

Background:

High-level protein overexpression is crucial for biotechnology but is often limited by sequence compatibility.
Previous analysis of 6,384 gene constructs identified sequence features and mRNA folding stability affecting protein yield.

Purpose of the Study:

To develop a predictive model for protein yield during overexpression in E. coli.
To create an optimized synonymous gene sequence generator for enhanced protein expression.
To experimentally validate the efficacy of optimized constructs for commercially relevant proteins.

Main Methods:

Analysis of sequence features and mRNA folding stability across a large dataset of gene constructs.
Development of a computational model to predict protein yield.
Implementation of the OPT.williams.edu server for prediction and sequence optimization.
Experimental validation of optimized constructs for eight commercial proteins.

Main Results:

A predictive model for protein yield was successfully developed.
The OPT.williams.edu server accurately predicts protein expression levels and generates optimized sequences.
Experimental results confirmed high protein yields for optimized constructs of commercially produced proteins.

Conclusions:

Sequence optimization is a viable strategy to significantly improve protein expression yields in E. coli.
The OPT server provides a valuable tool for researchers and biotechnologists seeking to maximize protein production.
This work demonstrates a data-driven approach to overcoming expression limitations in protein engineering.
