The same independence that drove Arnold to move out of her childhood home as a teenager also led to a large volume of absences from school and low grades. In spite of this, she made near perfect scores on standardized tests and was determined to attend Princeton University, the alma mater of her father. She applied as a mechanical engineering major and was accepted. Arnold's motivation behind studying engineering, as stated in her Nobel Prize interview, was that "[mechanical engineering] was the easiest option and the easiest way to get into Princeton University at the time and I never left".
After graduating from Princeton in 1979, Arnold worked as an engineer in South Korea and Brazil and at Colorado's Solar Energy Research Institute. At the Solar Energy Research Institute (now the National Renewable Energy Laboratory), she worked on designing solar energy facilities for remote locations and helped write United Nations (UN) position papers.
One advantage of directed evolution is that the mutations do not have to be completely random; instead, they can be random enough to discover unexplored potential, but not so random as to be inefficient. The number of possible mutation combinations is astronomical, but instead of just randomly trying to test as many as possible, she integrates her knowledge of biochemistry to narrow down the options, focusing on introducing mutations in areas of the protein that are likely to have the most positive effect on activity and avoiding areas in which mutations would likely be, at best, neutral and at worst, detrimental (such as disrupting proper protein folding).
Arnold applied directed evolution to the optimization of enzymes (although not the first person to do so, see e.g. Barry Hall). In her seminal work, published in 1993, she used the method to engineer a version of subtilisin E that was active in the organic solvent DMF, a highly unnatural environment. She carried out the work using four sequential rounds of mutagenesis of the enzyme's gene, expressed by bacteria, through error-prone PCR. After each round she screened the enzymes for their ability to hydrolyze the milk protein casein in the presence of DMF by growing the bacteria on agar plates containing casein and DMF. The bacteria secreted the enzyme and, if it were functional, it would hydrolyze the casein and produce a visible halo. She selected the bacteria that had the biggest halos and isolated their DNA for further rounds of mutagenesis. Using this method, she discovered an enzyme that had 256 times more activity in DMF than the original.
She has further developed her methods and applied them under different selection criteria in order to optimize enzymes for different functions. She showed that, whereas naturally evolved enzymes tend to function well at a narrow temperature range, enzymes could be produced using directed evolution that could function at both high and low temperatures. In addition to improving the existing functions of natural enzymes, Arnold has discovered enzymes that perform functions for which no previous specific enzyme existed, such as when she evolved cytochrome P450 to carry out cyclopropanation and carbene and nitrene transfer reactions.
In addition to evolving individual molecules, she has used directed evolution to co-evolve enzymes in biosynthetic pathways, such as those involved in the production of carotenoids and L-methionine in Escherichia coli (which has the potential to be used as a whole-cell biocatalyst). She has applied these methods to biofuel production. For example, she evolved bacteria to produce the biofuel isobutanol; it can be produced in E. coli bacteria, but the production pathway requires the cofactor NADPH, whereas E. coli makes the cofactor NADH. To circumvent this problem, she evolved the enzymes in the pathway to use NADH instead of NADPH, allowing for the production of isobutanol.
Arnold has also used directed evolution to discover highly specific and efficient enzymes that can be used as environmentally-friendly alternatives to some industrial chemical synthesis procedures. She, and others using her methods, have engineered enzymes that can carry out synthesis reactions more quickly, with fewer by-products, and in some cases eliminating the need for hazardous heavy metals.
She uses structure-guided protein recombination to combine parts of different proteins to form protein chimeras with unique functions. She developed computational methods, such as SCHEMA, to predict how the parts can be combined without disrupting their parental structure, so that the chimeras will fold properly, and then applies directed evolution to further mutate the chimeras to optimize their functions.
At Caltech, Arnold runs a laboratory that continues to study directed evolution and its applications in environmentally-friendly chemical synthesis and green/alternative energy, including the development of highly active enzymes (cellulolytic and biosynthetic enzymes) and microorganisms to convert renewable biomass to fuels and chemicals. A paper published in Science in 2019, with Inha Cho and Zhi-Jun Jia, has been retracted on January 2, 2020, as the results were found to be not reproducible.
Her hobbies include traveling, scuba diving, skiing, dirt-bike riding, and hiking.
She portrayed herself in the 18th episode "The Laureate Accumulation" of the 12th season of the TV series The Big Bang Theory. In September 2021 in the 10th anniversary of PME UChicago she jokingly claimed that this appearance was the greatest accolade of her life. She also appeared in a brief interview in the NOVA episode Beyond the Elements: Life. She was interviewed by Jim Al-Khalili on the BBC's The Life Scientific on September 6, 2022.
