  Structural and Functional Characterization of Plant Aminoaldehyde Dehydrogenase from Pisum sativum with a Broad Specificity for Natural and Synthetic Aminoaldehydes

  摘要：

  Aminoaldehyde dehydrogenases (AMADHs, EC 1.2.1.19) belong to the large aldehyde dehydrogenase (ALDH) superfamily, namely, the ALDH9 family. They oxidize polyamine-derived omega-aminoaldehydes to the corresponding omega-amino acids. Here, we report the first X-ray structures of plant AMADHs: two isoenzymes, PsAMADH1 and PsAMADH2, from Pisum sativum in complex with beta-nicotinamide adenine dinucleotide (NAD(+)) at 2.4 and 2.15 angstrom resolution, respectively. Both recombinant, proteins are dimeric and, similarly to other ALDHs, each monomer is composed of an oligomerization domain, a coenzyme binding domain and a catalytic domain. Each subunit binds NAD(+) as a coenzyme, contains a solvent-accessible C-terminal peroxisomal targeting signal (type 1) and a cation bound in the cavity close to the NAD(+) binding site. While the NAD(+) binding mode is classical for PsAMADH2, that for PsAMADH1 is unusual among ALDHs. A glycerol molecule occupies the substrate binding site and mimics a bound substrate. Structural analysis and substrate specificity study of both isoenzymes in combination with data published previously on other ALDH9 family members show that the established categorization of such enzymes into distinct groups based on substrate specificity is no more appropriate, because many of them seem capable of oxidizing a large spectrum of aminoaldehyde substrates. PsAMADH1 and PsAMADH2 can oxidize N,N,N-trimethyl-4-aminobutyraldehyde into gamma-butyrobetaine, which is the carnitine precursor in animal cells. This activity highly suggests that in addition to their contribution to the formation of compatible osmolytes such as glycine betaine, beta-alanine betaine and gamma-aminobutyric acid, AMADHs might participate in carnitine biosynthesis in plants.

  A new nucleoside antibiotic, mildiomycin D, was isolated from the culture broth of Streptoverticillium rimofaciens B-98891as a minor component. Themolecular formula of the antibiotic purified by silica gel and ion exchange resin columnchromatographies was determined to be C19H30N8O8• (2H2O) from its physicochemical data. The ultraviolet and infrared spectra were very similar to those ofmildiomycin, a major component. On the basis of 1H and 13C-NMRspectra and acidic hydrolysates of the compound, the chemical structure of the antibiotic was determined as a deoxy compound at the C8, position in mildiomycin. Mildiomycin D showed weak activities against Gram-positive and negative bacteria, phytopathogenic fungi and some yeasts, and its activity against Rhodotorula rubura was about 40% that of mildiomycin.

  Enzymes that catalyze hydroxylation of unactivated carbons normally contain heme and nonheme iron cofactors. By contrast, how a pyridoxal phosphate (PLP)-dependent enzyme could catalyze such a hydroxylation was unknown. Here, we investigate RohP, a PLP-dependent enzyme that converts l-arginine to (S)-4-hydroxy-2-ketoarginine. We determine that the RohP reaction consumes oxygen with stoichiometric release

  催化未活化碳羟基化的酶通常包含血红素和非血红素铁辅助因子。相比之下，磷酸吡ido醛（PLP）依赖性酶如何催化这种羟基化是未知的。在这里，我们研究RohP，一种PLP依赖性酶，可将1-精氨酸转化为（S）-4-羟基-2-酮精氨酸。我们确定RohP反应消耗化学计量的H 2 O 2释放氧气。为了理解这种不寻常的化学反应，我们获得了约1.5Å的分辨率结构，可沿催化循环捕获中间体。我们的数据表明RohP进行四电子氧化和立体定向烯烃水合以生成（S）配置的产品。连同我们对O 2，依赖PLP的l-精氨酸氧化酶的早期研究一起，我们的工作表明存在一条共同的途径导致l-精氨酸的氧化和羟基化产物。

  Keeping it basic: Arginine provides the exotic 4‐guanidinobutanoate starter unit for two different types of zwitterionic polyketide (an example for one type is shown in the picture) produced by the same Streptomyces bacterium. The three‐step precursor pathway is initiated by a remarkable decarboxylating monooxygenase with high specificity for arginine.
