However, to simplify the nomenclature and taking into account their metabolism, we classify them within the big group of the fatty acids and their simple derivatives rather than within the complex and phosphorylated lipids.
Long-chain acyl-CoA esters are substrates for a number of important enzymatic reactions and play a central role in the regulation of metabolism as allosteric regulators of several enzymes.

Enzymes are powerful catalysts. Unlike tedious multi-step chemical syntheses, enzyme-assisted reactions deliver 1) high yields of pure products and 2) molecules with the desired stereochemistry. Furthermore, this approach does not require toxic organic solvents (green chemistry). Thus, we took advantage of these efficient biocatalysts. We harvested the enzymatic activity of NAD-nucleosidase mutants for efficient gram-scale production of O-acetyl-ADP-ribose (OAADPR; Figure 2D). This molecule is a by-product of the sirtuin-catalyzed reactions. OAADPR was obtained through our in-line production (99% yield; Figure 2A). This set-up allows for easy and fast preparation of pure metabolite. Likewise, kinases were used to generate a phosphorylated derivative of Immucillin-A (Figure 3). ImmA-TP is a potent inhibitor of the newly described C–P lyase nucleosidase PhnI.

Better ways of making plastics also rely on biocatalytic methods, though finding a process that is energetically sustainable can be a challenge. Cargill Dow, a company based in Minnesota that makes polymers for textiles and packaging, using vegetation rather than petroleum, has produced a biodegradeable plastic called polylactic acid on a commercial scale. To do this, it uses a whole-cell biocatalyst system to make lactic acid by fermenting corn sugar. Incorporating the biocatalytic step avoids complications that have hampered production in the past, and requires substantially less fossil-fuel resources than similar plastics. A maize-based fermentation process developed by DuPont and Genencor combines from three different organisms to create a non-petroleum-based route to 1,3-propandiol, a plastic used to make textile fibres.
Poly(lactic acid) (PLA) depolymerases are categorized into protease-type and lipase-type (7). We examined the literature and found sequences for one enzyme from each type.

The efficiency of degrading Polylactic acid (PLA) is important for the performance of MAPLE. Therefore, we chose a strong enzyme Proteinase K which is suggested by many literature as an efficient PLA degrading enzyme. We performed several assays in order to determine the kinetic properties of Proteinase K. The PLA degradation model was then built based on the experimental results.

The world faces the challenge to develop sustainable technologies to replace thousands of products that have been generated from fossil fuels. Microbial cell factories serve as promising alternatives for the production of diverse commodity chemicals and biofuels from renewable resources. For example, polylactic acid (PLA) with its biodegradable properties is a sustainable, environmentally friendly alternative to polyethylene. At present, PLA microbial production is mainly dependent on food crops such as corn and sugarcane. Moreover, optically pure isomers of lactic acid are required for the production of PLA, where D-lactic acid controls the thermochemical and physical properties of PLA. Henceforth, production of D-lactic acid through a more sustainable source (CO2) is desirable.

We have performed metabolic engineering on Synechocystis sp. PCC 6803 for the phototrophic synthesis of optically pure D-lactic acid from CO2. Synthesis of optically pure D-lactic acid was achieved by utilizing a recently discovered enzyme (i.e., a mutated glycerol dehydrogenase, GlyDH*). Significant improvements in D-lactic acid synthesis were achieved through codon optimization and by balancing the cofactor (NADH) availability through the heterologous expression of a soluble transhydrogenase. We have also discovered that addition of acetate to the cultures improved lactic acid production. More interestingly, 13C-pathway analysis revealed that acetate was not used for the synthesis of lactic acid, but was mainly used for synthesis of certain biomass building blocks (such as leucine and glutamate). Finally, the optimal strain was able to accumulate 1.14 g/L (photoautotrophic condition) and 2.17 g/L (phototrophic condition with acetate) of D-lactate in 24 days.
