Abstract
Copper amine oxidases (CAOs) catalyze the oxidative deamination of primary amines to their corresponding aldehydes, with the concomitant reduction of O(2) to H(2)O(2). Catalysis requires two cofactors: a mononuclear copper center and the cofactor 2,4,5-trihydroxyphenylalanine quinone (TPQ). TPQ is synthesized through the post-translational modification of an endogenous tyrosine residue and requires only oxygen and copper to proceed. TPQ biogenesis in CAO can be supported by alternate metals, albeit at decreased rates. A variety of factors are thought to contribute to the degree to which a metal can support TPQ biogenesis, including Lewis acidity, redox potential and electrostatic stabilization capability. The crystal structure has been solved of one of two characterized CAOs from the yeast Hansenula polymorpha (HPAO-1) in its metal-free (apo) form, which contains an unmodified precursor tyrosine residue instead of fully processed TPQ (HPAO-1 was denoted HPAO in the literature prior to 2010). Structures of apoHPAO-1 in complex with Cu(I) and Co(II) have also been solved, providing structural insight into metal binding prior to biogenesis.

Abstract
Tropoelastin is encoded by a single human gene that spans 36 exons and is oxidized in vivo by mammalian lysyl oxidase at the epsilon amino group of available lysines to give the adipic semialdehyde, which then facilitates covalent cross-link formation in an enzyme-free process involving tropoelastin association. We demonstrate here that this process is effectively modeled by a two protein component system using purified lysyl oxidase from the yeast Pichia pastoris to facilitate the oxidation and subsequent cross-linking of recombinant human tropoelastin. The oxidized human tropoelastin forms an elastin-like polymer (EL) that is elastic, shows hydrogel behavior and contains typical elastin cross-links including lysinonorleucine, allysine aldol, and desmosine. Protease digestion and subsequent mass-spectrometry analysis of multiple ELs allowed for the identification of specific intra- and inter-molecular cross-links, leading to a model of the molecular architecture of elastin assembly in vitro. Specific intra-molecular cross-links were confined to the region of tropoelastin encoded by exons 6-15. Inter-molecular cross-links were prevalent between the regions encoded by exons 19-25. We find that assembly of tropoelastin molecules in ELs are highly enriched for a defined subset of cross-links.

Abstract
Copper-containing amine oxidase extracted from bovine serum (BSAO) was crystallized and its three-dimensional structure at 2.37A resolution is described. The biological unit of BSAO is a homodimer, formed by two monomers related to each other by a non-crystallographic 2-fold axis. Each monomer is composed of three domains, similar to those of other amine oxidases from lower species. The two monomers are structurally equivalent, despite some minor differences at the two active sites. A large funnel allows access of substrates to the active-site; another cavity, accessible to the solvent, is also present between the two monomers; this second cavity could allow the entrance of molecular oxygen necessary for the oxidative reaction. Some sugar residues, bound to Asn, were still present and visible in the electron density map, in spite of the exhaustive deglycosylation necessary to grow the crystals. The comparison of the BSAO structure with those of other resolved AO structures shows strong dissimilarities in the architecture and charge distribution of the cavities leading to the active-site, possibly explaining the differences in substrate specificity.

Abstract
Pichia pastoris lysyl oxidase (PPLO) is unique among the structurally characterized copper amine oxidases in being able to oxidize the side chain of lysine residues in polypeptides. Remarkably, the yeast PPLO is nearly as effective in oxidizing a mammalian tropoelastin substrate as is a true mammalian lysyl oxidase isolated from bovine aorta. Thus, PPLO is functionally related to the copper-containing lysyl oxidases despite the lack of any significant sequence similarity with these enzymes. The structure of PPLO has been determined at 1.65 A resolution. PPLO is a homodimer in which each subunit contains a Type II copper atom and a topaquinone cofactor (TPQ) formed by the posttranslational modification of a tyrosine residue. While PPLO has tertiary and quaternary topologies similar to those found in other quinone-containing copper amine oxidases, its active site is substantially more exposed and accessible. The structural elements that are responsible for the accessibility of the active site are identified and discussed.

Abstract
Glyoxysomes are present in etiolated cotyledons and contain enzymes for gluconeogenesis, which constitutes the major function of glyoxysomes. However, 281 genes seemingly related to peroxisomal functions occur in the Arabidopsis genome, implying that many unidentified proteins are present in glyoxysomes. To better understand the functions of glyoxysomes, we performed glyoxysomal proteomic analysis of etiolated Arabidopsis cotyledons. Nineteen proteins were identified as glyoxysomal proteins, including 13 novel proteins, one of which is glyoxysomal protein kinase 1 (GPK1). We cloned GPK1 cDNA by RT-PCR and characterized GPK1. The amino acid sequence deduced from GPK1 cDNA has a hydrophobic region, a putative protein kinase domain, and a possible PTS1 motif. Immunoblot analysis using fractions collected on a Percoll density gradient confirmed that GPK1 is localized in glyoxysomes. Analysis of suborganellar localization and protease sensitivity showed that GPK1 is localized on glyoxysomal membranes as a peripheral membrane protein and that the putative kinase domain is located inside the glyoxysomes. Glyoxysomal proteins are phosphorylated well in the presence of various metal ions and [g-32P]ATP, and one of them is identified as thiolase by immunoprecipitation. Immuno-inhibition of phosphorylation in glyoxysomes suggested that GPK1 phosphorylates a 40-kDa protein. These results show that protein phosphorylation systems are operating in glyoxysomes.

Abstract
Potential inhibitory effects of the clinically utilized monoamine oxidase inhibitor tranylcypromine (TCP) on mammalian, plant, bacterial, and fungal copper-containing amine oxidases have been examined. The following enzymes have been investigated: human kidney diamine oxidase (HKAO), bovine plasma amine oxidase (BPAO), equine plasma amine oxidase (EPAO), pea seedling amine oxidase (PSAO), Arthrobacter globiformis amine oxidase (AGAO), and Pichia pastoris lysyl oxidase (PPLO). Only BPAO, EPAO, and AGAO were found to lose significant levels of activity when incubated with varying amounts of TCP. Inhibition of BPAO was completely reversible, with dialysis restoring full activity. TCP inhibition of AGAO was also found to be ultimately reversible; however, dialysis did not remove all bound compounds. Chemical displacement with either substrate or a substrate analogue successfully removed all bound TCP, indicating that this compound has a high affinity for the active site of AGAO. The notable lack of TCP inhibition on HKAO argues against the inhibition of diamine oxidase as a potential source for some of the deleterious side effects occurring in patients treated with this antidepressant. The marked differences observed in behavior among these enzymes speaks to the importance of intrinsic structural differences between the active sites of copper amine oxidases (CAO) which affect reactivity with a given inhibitor.

Abstract
Four substrate analogs, 4-(2-naphthyloxy)-2-butyn-1-amine (1), 1,4-diamino-2-chloro-2-butene (2), 1,6-diamino-2,4-hexadiyne (3), and 2-chloro-5-phthalimidopentylamine (4) have been tested as inhibitors against mammalian, plant, bacterial, and fungal copper-containing amine oxidases: bovine plasma amine oxidase (BPAO), equine plasma amine oxidase (EPAO), pea seedling amine oxidase (PSAO), Arthrobacter globiformis amine oxidase (AGAO), Escherichia coli amine oxidase (ECAO), and Pichia pastoris lysyl oxidase (PPLO). Reactions of 1,4-diamino-2-butyne with selected amine oxidases were also examined. Each substrate analog contains a functional group that chemical precedent suggests could produce mechanism-based inactivation. Striking differences in selectivity and rates of inactivation were observed. For example, between two closely related plasma enzymes, BPAO is more sensitive than EPAO to 1 and 3, while the reverse is true for 2 and 4. In general, inactivation appears to arise in some cases from TPQ cofactor modification and in other cases from alkylation of protein residues in a manner that blocks access of substrate to the active site. Notably, 1 completely inhibits AGAO at stoichiometric concentrations and is not a substrate, but is an excellent substrate of PSAO and inhibition is observed only at very high concentrations. Structural models of 1 in Schiff base linkage to the TPQ cofactor in AGAO and PSAO (for which crystal structures are available) reveal substantial differences in the degree of interaction of bound 1 with side-chain residues, consistent with the widely divergent activities. Collectively, these results suggest that the development of highly selective amine oxidase inhibitors is feasible.

Abstract
Lysyl oxidase from Pichia pastoris has been successfully overexpressed. EPR and resonance Raman experiments have shown that copper and TPQ are present, respectively. Lysyl oxidase from P. pastoris has a similar substrate specificity to the mammalian enzyme (both have been shown to oxidize peptidyl lysine residues) and is 30% identical to the human kidney diamine oxidase (the highest of any non-mammalian source). This enzyme also has a relatively broad substrate specificity compared to other amine oxidases. Molecular modeling data suggest that the substrate channel in lysyl oxidase from P. pastoris permits greater active site access than observed in structurally-characterized amine oxidases. This larger channel may account for the diversity of substrates that are turned over by this enzyme.

Abstract
The polyamines spermine, spermidine, and putrescine are small organic molecules one or more of which are present in all living organisms. Many natural products contain polyamine residues. Polyamines are synthesized by a highly regulated pathway from arginine or ornithine and also can be transported in and out of cells. Polyamines are degraded to a variety of compounds the functions of which are largely unknown. Polyamines influence the transcriptional and translational stages of protein synthesis, stabilize membranes, and, in mammalian systems, modulate neurophysiological functions and may act as intracellular messengers. However, at the molecular level the mode of action of the polyamines is largely unknown.

Abstract
A copper amine oxidase from Pichia pastoris is the only known non-mammalian lysyl oxidase [Tur, S.S. and Lerch, K. (1988) FEBS Lett. 238, 74-76]. Recently, the cofactor in mammalian lysyl oxidase has been identified as a novel lysine tyrosylquinone moiety [Wang, S.X., Mure, M., Medzihradszky, K.F., Burlingame, A.L., Brown, D.E., Dooley, D.M., Smith, A.J., Kagan, H.M. and Klinman, J.P. (1996) Science 273, 1078-1084]. In order to identify the cofactor in P. pastoris lysyl oxidase, we have isolated the phenylhydrazone-derivative of the active-site peptide. This peptide has the active-site sequence conserved among topa quinone containing amine oxidases. The resonance Raman spectra of the phenylhydrazone derivatives of the enzyme, active-site peptide, and a topa quinone model compound are essentially identical. Collectively, these results establish that P. pastoris lysyl oxidase is a topa quinone enzyme.

Abstract
Two distinct quinoprotein amine oxidases were found in Aspergillus niger mycelia grown on n-butylamine medium and purified using chromatographic techniques. The respective enzymes were termed AO-I, which had already been isolated, and AO-II, a new enzyme found in this study. HPLC indicated that their molecular masses are 150 kDa and 80 kDa, respectively. On SDS/PAGE, the enzymes gave a similar but distinct mobility, which corresponds to 75 kDa for the subunit dimeric AO-I and 80 kDa for monomeric AO-II. The absorption spectra of both enzymes were different from each other; the absorption maxima in the visible region were at 490 nm for AO-I and 420 nm for AO-II. The enzymes showed positive quinone staining, comparable substrate specificity, and sensitivity to inhibitors typical for copper/topa quinone-containing amine oxidases, but they had different copper contents and also differed in their N-terminal sequences. Their peptide maps showed almost identical patterns, with the exception of two additional bands for AO-II. Among the peptides obtained from digestion of AO-II, peptides with sequences corresponding to the N-terminal part of AO-I were detected. Polyclonal antibodies raised against AO-I and AO-II recognized both enzymes, but with different specificities. Using precipitation with AO-I, the antibody prepared against AO-II was purified and was shown to be specific only for AO-II. The cDNA of AO-I was cloned and sequenced. A highly conserved tetrapeptide sequence, Asn-Tyr-Glu-Tyr, was identified in which the first tyrosine residue (Tyr404) that could be converted to topa quinone was present in the 670-residue deduced amino acid sequence. Northern blot analysis indicated that AO-I was highly expressed in A. niger grown on n-butylamine as a single nitrogen source. Genomic Southern blot analysis confirmed that both enzymes are likely to be encoded by the same gene.

Abstract
Upon induction with various amine sources, two different amine oxidases are expressed in the filamentous fungus Aspergillus niger. The enzymes which can be separated by anion exchange chromatography exhibit a similar substrate specificity pattern. From cofactor and inhibitor analysis it was found that one amine oxidase is identical to the earlier reported copper-containing amine oxidase (Yamada, H., Adachi, O. and Ogata, K. (1965) Agric. Biol. Chem. 29, 912-917) with 6-hydroxydopa (TOPA) quinone as the active site cofactor. The second form is a hitherto unknown flavoprotein of 55 kDa, which shows many of the characteristic properties of the mammalian monoamine oxidases (MAO). From substrate specificity and inhibitor susceptibility, it is suggested that the monoamine oxidase from A. niger (MAO-N) is a prototype of the two mammalian enzymes, MAO-A and MAO-B. A partial cDNA clone which encodes an amino-terminal peptide of 53 amino acid residues was identified by lambda gt11 immunoscreening. The consensus sequence of the putative flavin adenine dinucleotide (FAD) binding site is found within this sequence.

Abstract
We have cloned the AMO gene, encoding the microbody matrix enzyme amine oxidase (EC 1.4.3.6) from the yeast Hansenula polymorpha. The gene was isolated by differential screening of a cDNA library, immunoselection, and subsequent screening of a H. polymorpha genomic library. The nucleotide sequence of a 3.6 kilobase stretch of DNA containing the amine oxidase (AMO) gene was determined. The AMO gene contains an open reading frame of 692 amino acids, with a relative molecular mass of 77,435. The 5' and 3' ends of the gene were mapped and show that the transcribed region measures 2134 nucleotides. The derived amino-acid sequence was confirmed by sequencing an internal proteolytic fragment of the purified protein. Amine oxidase contains the tripeptide sequence Ser-Arg-Leu, located 9 residues from the carboxy terminus, which may represent the topogenic signal for protein import into microbodies.

Abstract
Benzylamine oxidase (EC 1.4.3.6) from the yeast Pichia pastoris is a 106 kDa quinoprotein containing one copper atom per molecule. It has a broad substrate specificity ranging from butylamine to peptidyl lysine in collagen and elastin. The kinetic data obtained using lysine-containing model peptides as substrates indicate an astonishing similarity to mammalian lysyloxidase. This similarity is further supported by the inhibition of both enzymes with beta-aminopropionitrile.

Abstract
In the crude homogenates of three different strains (C3H, Swiss, C57b) of mouse kidney the exposure to a millimolar concentration of clorgyline reveals a benzylamine oxidative deaminating activity that is due to a clorgyline resistant amine oxidase (CRAO). In the three strains this CRAO activity shows a low sensitivity to semicarbazide and to alpha- amiguanidine. In the C3H mouse kidney the glycoprotein nature of the CRAO was established from affinity chromatography with immobilized concanavalin A. Studies of this activity in the C3H mouse kidney revealed the presence of a reversible inhibitor which is precipitated by ammonium sulphate between 35-55% of saturation. The presence of this inhibitor precludes accurate measurement of the CRAO distribution in the different subcellular fractions. The enzyme purified by affinity chromatography, is semicarbazide insensitive. This is the first observation of the presence of a CRAO-semicarbazide insensitive activity in a tissue. The fact that "original homogenate" and the subcellular fractions show some sensitivity to semicarbazide also indicates that a semicarbazide-sensitive amine oxidase (SSAO) is present in the C3H mouse kidney.

Abstract
The amine oxidase from Trichosporon cutaneum X4 grown on ethylamine as carbon, nitrogen and energy source was purified to near homogeneity. The purified enzyme showed the highest resistance to heat of any amine oxidase hitherto characterized from a yeast (half-life at 62 degrees C, 14 min). Measurement of kinetic parameters as a function of carbon chain length showed results typical of a benzylamine oxidase. Both non-denaturing- and sodium dodecyl sulphate-polyacrylamide gel electrophoresis showed multiple bands, and dimethyl suberimidate cross-linking studies revealed that the enzyme consisted of multimers of two polypeptide chains of Mr respectively 19,000 and 26,000. The smallest structure to show activity probably contained two of each kind of subunit.

Abstract
The maximum growth rate of Trichosporon cutaneum CBS 8111 in chemostat cultures was 0.185 h-1 on ethylamine and 0.21 h-1 on butylamine, that of Candida famata CBS 8109 was 0.32 h-1 on putrescine. The amine oxidation pattern of the ascomycetous strains studied, viz. Candida famata CBS 8109, Stephanoascus ciferrii CBS 4856 and Trichosporon adeninovorans CBS 8244 was independent of the amine that had been used as the growth substrate. It resembled that of benzylamine/putrescine oxidase found in other ascomycetous yeasts. However, differences in pH optimum and substrate specificity were observed between the amine-oxidizing systems of these three species. The amine oxidation pattern of cell-free extracts of Trichosporon cutaneum CBS 8111 varied with the amine that was used as growth substrate. The enzyme system produced by Cryptococcus laurentii CBS 7140 failed to oxidize isobutylamine and benzylamine, and showed a high pH optimum. The synthesis of amine oxidase in the four yeast strains studied was not repressed by ammonium chloride and was weakly repressed by glucose but was strongly repressed if both compounds were present in the growth medium.

Abstract
Under conditions known to separate methylamine oxidase from benzylamine oxidase in other yeast strains, only a single oxidase could be detected in Sporobolomyces albo-rubescens. This occurred irrespective of whether methylamine or n-butylamine was the nitrogen source for growth. The oxidase did not attack benzylamine. It was concluded that this organism can only produce a methylamine oxidase. The enzyme was purified to 90% homogeneity and found to have properties significantly different from the methylamine oxidases previously characterised. It lost only 40% of its activity in 30 min at 45 degrees C, whereas methylamine oxidases previously described had half-lives of from 2 to 9 min at 45 degrees C. It showed also a lower activity with short chain 1-aminoalkanes and a higher activity with longer chain 1-aminoalkanes than other methylamine oxidases, and had a significantly smaller subunit molecular weight (57,000 compared with 80,000).

Abstract
The yeast Candida boidinii when grown on spermidine, diaminopropane, putrescine or cadaverine as sole nitrogen source contains an N-acetyltransferase capable of acetylating the primary amino groups of spermine, spermidine, acetylspermidines, acetylputrescine and alpha, omega-diaminoalkanes. In the case of spermidine, the products were N1-acetylspermidine and N8-acetylspermidine in the ratio 50:45 with traces of other unidentified products. The enzyme was partially purified and the stoichiometry determined, together with apparent Km and V values for a number of substrates. The pH optimum was about 8.8 for putrescine and 9.3 for spermidine. The unstable enzyme was partially stabilized by 10% (v/v) glycerol or bovine serum albumin (5 mg/ml). The kinetic parameters were determined with putrescine as substrate and the mechanism shown to be of the sequential type. The enzyme was shown to be located in the mitochondria of C. boidinii, in contrast to mammalian N-acetyltransferases. The enzyme was found in a number of other yeast species when grown on spermidine or putrescine, but was only present in those species that had previously been found to contain polyamine oxidase. It is suggested that in C. boidinii, as in mammals, acetylation of spermidine and putrescine must precede their catabolism.
