Pers.) provides the initial step by which mannitol is committed to central metabolism and plays a critical role in regulating mannitol concentration in the plant. The pH optimum for mannitol oxidation occurs at pH 9.5 whereas the optimum for mannose reduction occurs at pH 6.5. Michaelis–Menten kinetics were exhibited for mannitol and NAD with Km values of 64 and 0.14 mM, respectively at pH 9.5. The Km for mannose and NADH were 745 mM and 1.27 μM, respectively at pH 6.5. The high Km for mannose is consistent with a reaction in situ favoring mannitol oxidation rather than mannose reduction. The observed down-regulation of MTD in salt stressed celery is not due to a direct inhibition by NaCl or macronutrients. Inhibition by the chelator 1,10-phenanthroline suggests that zinc is required for MTD activity. Reducing agents DTT, DTE and β-mercaptoethanol inactivated MTD reversibly. At pH 7.0, ADP and to a lesser extend AMP and ATP were competitive inhibitors, with respect to NAD, having apparent Ki's of 0.24, 0.64 and 1.10 mM, respectively.}, number={1}, journal={PLANT SCIENCE}, author={Stoop, JMH and Williamson, JD and Conkling, MA and MacKay, JJ and Pharr, DM}, year={1998}, month={Jan}, pages={43–51} }

The lethal gene of the suicide system consists of the three-gene restriction cassette LlaIR+, which is lethal across a wide range of gram-positive bacteria. The phage-inducible trigger promoter (phi31P) and the LlaIR+ restriction cassette were cloned in Escherichia coli on a high-copy-number replicon to generate pTRK414H. Restriction activity was not apparent in E. coli or L. lactis prior to phage infection. In phage challenges of L. lactis(pTRK414H) with phi31, the efficiency of plaquing was lowered to 10(-4) and accompanied by a fourfold reduction in burst size. Center-of-infection assays revealed that only 15% of infected cells released progeny phage. In addition to phage phi31, the phi31P/LlaIR+ suicide cassette also inhibited four phi31-derived recombinant phages at levels at least 10-fold greater than that of phi31. The phi31P/LlaIR+-based suicide system is a genetically engineered form of abortive infection that traps and eliminates phages potentially evolving in fermentation environments by destroying the phage genome and killing the propagation host. This type of phage-triggered suicide system could be designed for any bacterium-phage combination, given a universal lethal gene and an inducible promoter which is triggered by the infecting bacteriophage.}, number={21}, journal={JOURNAL OF BACTERIOLOGY}, author={Djordjevic, GM and OSullivan, DJ and Walker, SA and Conkling, MA and Klaenhammer, TR}, year={1997}, month={Nov}, pages={6741–6748} }

Endogenous regulation of the enzyme activity in response to environmental cues is critical in modulating tissue concentration of mannitol, which, importantly, contributes to stress tolerance of celery. The enzyme was purified to homogeneity from celery suspension cultures grown on D-mannitol as the carbon source. Mannitol dehydrogenase was purified 589-fold to a specific activity of 365 [mu]mol h-1 mg-1 protein with a 37% yield of enzyme activity present in the crude extract. A highly efficient and simple purification protocol was developed involving polyethylene glycol fractionation, diethylaminoethyl-anion-exchange chromatography, and NAD-agarose affinity chromatography using NAD gradient elution. Sodium dodecyl sulfate gel electrophoresis of the final preparation revealed a single 40-kD protein. The molecular mass of the native protein was determined to be approximately 43 kD, indicating that the enzyme is a monomer. Polyclonal antibodies raised against the enzyme inhibited enzymatic activity of purified mannitol dehydrogenase. Immunoblots of crude protein extracts from mannitol-grown celery cells and sink tissues of celery, celeriac, and parsley subjected to sodium dodecyl sulfate gel electrophoresis showed a single major immunoreactive 40-kD protein.}, number={3}, journal={PLANT PHYSIOLOGY}, author={STOOP, JMH and WILLAMSON, JD and CONKLING, MA and PHARR, DM}, year={1995}, month={Jul}, pages={1219–1225} }

Celery (Apium graveolens L.), a plant that forms mannitol photosynthetically, has high photosynthetic rates thought to results from intrinsic differences in the biosynthesis of hexitols vs. sugars. Celery also exhibits high salt tolerance due to the function of mannitol as an osmoprotectant. A mannitol catabolic enzyme that oxidizes mannitol to mannose (mannitol dehydrogenase, MTD) has been identified. In celery plants, MTD activity and tissue mannitol concentration are inversely related. MTD provides the initial step by which translocated mannitol is committed to central metabolism and, by regulating mannitol pool size, is important in regulating salt tolerance at the cellular level. We have now isolated, sequenced, and characterized a Mtd cDNA from celery. Analyses showed that Mtd RNA was more abundant in cells grown on mannitol and less abundant in salt-stressed cells. A protein database search revealed that the previously described ELI3 pathogenesis-related proteins from parsley and Arabidopsis are MTDs. Treatment of celery cells with salicylic acid resulted in increased MTD activity and RNA. Increased MTD activity results in an increased ability to utilize mannitol. Among other effects, this may provide an additional source of carbon and energy for response to pathogen attack. These responses of the primary enzyme controlling mannitol pool size reflect the importance of mannitol metabolism in plant responses to divergent types of environmental stress.}, number={16}, journal={PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA}, author={WILLIAMSON, JD and STOOP, JMH and MASSEL, MO and CONKLING, MA and PHARR, DM}, year={1995}, month={Aug}, pages={7148–7152} }
