The structural basis of ordered substrate binding by serotonin N-acetyltransferase: enzyme complex at 1.8 A resolution with a bisubstrate analog. (1/43)

Serotonin N-acetyltransferase, a member of the GNAT acetyltransferase superfamily, is the penultimate enzyme in the conversion of serotonin to melatonin, the circadian neurohormone. Comparison of the structures of the substrate-free enzyme and the complex with a bisubstrate analog, coenzyme A-S-acetyltryptamine, demonstrates that acetyl coenzyme A (AcCoA) binding is accompanied by a large conformational change that in turn leads to the formation of the serotonin-binding site. The structure of the complex also provides insight into how the enzyme may facilitate acetyl transfer. A water-filled channel leading from the active site to the surface provides a pathway for proton removal following amine deprotonation. Furthermore, structural and mutagenesis results indicate an important role for Tyr-168 in catalysis.  (+info)

Melatonin, its precursors, and synthesizing enzyme activities in the human ovary. (2/43)

The presence of melatonin (N-acetyl-5-methoxytryptamine) and its precursors, serotonin (5-hydroxytryptamine) and N-acetylserotonin, was demonstrated in extracts of human ovary using reverse-phase high-performance liquid chromatography coupled with fluorometric detection. In addition, activities of two melatonin-synthesizing enzymes, arylalkylamine N-acetyltransferase (NAT) and hydroxyindole-O-methyltransferase (HIOMT), were found in human ovary homogenates. The apparent Michaelis constants for the substrates of NAT and HIOMT in the human ovary were similar to those reported for the pineal glands of humans and other mammals. These findings strongly suggest that the human ovary, like the pineal gland, may synthesize melatonin from serotonin by the sequential action of NAT and HIOMT.  (+info)

Genetic variability in plasma melatonin in sheep is due to pineal weight, not to variations in enzyme activities. (3/43)

This study was conducted to determine the origin of the high variability in the mean nocturnal plasma melatonin concentration (MC) in sheep. Two extreme groups of 25 lambs each [low (L) and high (H)] were obtained by calculating their genetic value on the basis of the MC of their parents. The MC of lambs was significantly higher in the H group than in the L group (L: 189.7 +/- 24.4 vs. H: 344.1 +/- 33.0 pg/ml, P < 0.001). Within each group, 13 lambs were slaughtered during the day (D) and 12 lambs during the night (N). Pineal weight was significantly higher in the H group than in the L group (L: 83.5 +/- 6.7 vs. H: 119.1 +/- 9.2 mg, P < 0.01) but did not differ between D and N. The amount of melatonin released in vitro per milligram of pineal gland, the arylalkylamine N-acetyltransferase (AANAT) activity, the AANAT protein content, and the level of AANAT mRNA differed significantly between D and N but not with genetic group. Hydroxyindole O-methyltransferase activity did not differ significantly between D and N or between genetic groups. Therefore, the genetic difference in MC between the two groups of lambs was attributed to a difference in pineal size, not in enzymatic activity of the pinealocytes.  (+info)

Identification of highly elevated levels of melatonin in bone marrow: its origin and significance. (4/43)

Bone marrow is an important tissue in generation of immunocompetent and peripheral blood cells. The progenitors of hematopoietic cells in bone marrow exhibit continuous proliferation and differentiation and they are highly vulnerable to acute or chronic oxidative stress. In this investigation, highly elevated levels of the antioxidant melatonin were identified in rat bone marrow using immunocytochemistry, radioimmunoassay, high performance liquid chromatography with electrochemical detection and mass spectrometry. Night-time melatonin concentrations (expressed as pg melatonin/mg protein) in the bone marrow of rats were roughly two orders of magnitude higher than those in peripheral blood. Measurement of the activities of the two enzymes (N-acetyltransferase (NAT) and hydroxyindole-O-methoxyltransferase (HIOMT)) which synthesize melatonin from serotonin showed that bone marrow cells have measurable NAT activity, but they have very low levels of HIOMT activity (at the one time they were measured). From these studies we could not definitively determine whether melatonin was produced in bone marrow cells or elsewhere. To investigate the potential pineal origin of bone marrow melatonin, long-term (8-month) pinealectomized rats were used to ascertain if the pineal gland is the primary source of this antioxidant. The bone marrow of pinealectomized rats, however, still exhibited high levels of melatonin. These results indicate that a major portion of the bone marrow's melatonin is of extrapineal origin. Immunocytochemistry clearly showed a positive melatonin reaction intracellularly in bone marrow cells. A melatonin concentrating mechanism in these cells is suggested by these findings and this may involve a specific melatonin binding protein. Since melatonin is an endogenous free radical scavenger and an immune-enhancing agent, the high levels of melatonin in bone marrow cells may provide on-site protection to reduce oxidative damage to these highly vulnerable hematopoietic cells and may enhance the immune capacity of cells such as lymphocytes.  (+info)

Regulation of hydroxyindole-O-methyltransferase gene expression in Japanese quail (Coturnix coturnix japonica). (5/43)

Hydroxyindole-O-methyltrasferase (HIOMT) plays an important role as the final enzyme in the synthesis of melatonin. In this study, the expression of the HIOMT gene in Japanese quail was investigated with respect to tissue distribution and the effects of light and vitamin A deficiency. HIOMT mRNA in the pineal gland and eye had a clear daily rhythm with peak values in daytime. The testis also contained a detectable amount of HIOMT mRNA, which did not display a rhythmic change over a 24-h period. When birds were rendered vitamin A deficient through feeding with a vitamin A-free diet, the daily rhythm of the HIOMT gene almost disappeared in both the pineal gland and eye due to increases in the nighttime values. Our previous observations and these results suggest that vitamin A and a photo-signal are required to maintain the rhythmic expression of the HIOMT gene as well as the arylalkylamine N-acetyltransferase gene.  (+info)

Conversion of L-tryptophan to serotonin and melatonin in human melanoma cells. (6/43)

We showed in human melanoma cells tryptophan hydroxylase (TPH) and hydroxyindole methyltransferase genes expression with the sequential enzymatic activities of TPH, serotonin (Ser) N-acetyltransferase and hydroxyindole methyltransferase. The presence of the products Ser, 5OH-tryptophan, N-acetylserotonin, melatonin (Mel), 5-methoxytryptamine and 5-methoxytryptophol was documented by liquid chromatography-mass spectrometry. Thus, human melanoma cells can synthesize and metabolize Ser and Mel.  (+info)

Serotoninergic and melatoninergic systems are fully expressed in human skin. (7/43)

We investigated the cutaneous expression of genes and enzymes responsible for the multistep conversion of tryptophan to serotonin and further to melatonin. Samples tested were human skin, normal and pathologic (basal cell carcinoma and melanoma), cultured normal epidermal and follicular melanocytes, melanoma cell lines, normal neonatal and adult epidermal and follicular keratinocytes, squamous cell carcinoma cells, and fibroblasts from dermis and follicular papilla. The majority of the samples showed simultaneous expression of the genes for tryptophan hydroxylase, arylalkylamine N-acetyltransferase (AANAT), and hydroxyindole-O-methyltransferase (HIOMT). The products of AANAT activity were identified by RP-HPLC with fluorimetric detection in human skin and in cultured normal and malignant melanocytes and immortalized keratinocytes; HIOMT activity was detected in human skin, keratinocytes, and melanoma cells. N-acetylserotonin (NAS) was detected by RP-HPLC in human skin extracts. NAS identity was confirmed further by LC/MS in keratinocytes. In conclusion, we provide evidence that the human skin expresses intrinsic serotonin and melatonin biosynthetic pathways.  (+info)

Molecular cloning and nucleotide sequence of a cDNA encoding hydroxyindole O-methyltransferase from chicken pineal gland. (8/43)

Hydroxyindole O-methyltransferase (EC 2.1.1.4) is the enzyme that catalyses the synthesis of melatonin in the pineal gland and in the retina. Polyadenylated RNA from chicken pineal glands was used to prepare a cDNA library in lambda gt11. The library was screened with an antiserum directed against chicken hydroxyindole O-methyltransferase, and one cDNA clone was isolated. The fusion protein expressed by phage lysogens was identified on Western blots as a 165 kDA immunoreactive protein (beta-galactosidase, 110 kDa; hydroxyindole O-methyltransferase, 38 kDa). The fusion protein exhibited hydroxyindole O-methyltransferase activity. Its Km values for N-acetyl-5-hydroxytryptamine and S-adenosylmethionine were 5 times those of the natural enzyme. The intrinsic activity of the fusion protein was approx. 0.25% that of the natural enzyme. The cDNA consisted of 1436 nucleotides, including a 1038-nucleotide sequence encoding a full-length 346-amino-acid hydroxyindole O-methyltransferase. Comparison with bovine hydroxyindole O-methyltransferase [Ishida, Obinata & Deguchi (1987) J. Biol. Chem. 262, 2895-2899] revealed 52% identity in nucleotide sequences and 44% identity in peptide sequences. Northern-blot analysis revealed the presence of hydroxyindole O-methyltransferase mRNA transcripts in chicken pineal gland and retina, but not in the telencephalon.  (+info)

Therefore, the objective of this study was to test for the existence of visual pigment in the chicken pineal by means of the identification of 11-cis-retinal in this organ. 11-cis- and all-trans retinoids were extracted from light- and dark-adapted chicken pineals and analyzed by high performance liquid chromatography (HPLC) using the formaldehyde method. 11-cis-Retinal was initially identified by coelution with an authentic standard. Further characterization was carried out by collecting the retinal from the HPLC eluant, subjecting it to reduction by ...
In vertebrates, the essential amino acid L-tryptophan is the precursor of 5-methoxyindoles, or indolamines/tryptamines, including melatonin (N-acetyl-5-methoxytryptamine), through the intermediate serotonin (5-HT, 5-hydroxytryptamine) and the activity of hydroxyindole-O-methyltransferase (HIOMT) [14]. In mammals, melatonin is synthesized in the pineal gland, predominantly during the night-time, although it can be also produced in other organs, such as retina, gastrointestinal tract, lymphocytes and bone marrow cells. Conversely, light at night has an inhibitory effect on pineal melatonin biosynthesis which is initiated by the uptake of tryptophan from the circulation into pinealocytes [15]. Once synthesized, melatonin is not stored in the pineal cells, but it is released into the bloodstream with a circadian rhythm, from which it reaches other body fluids, including urine, saliva, cerebrospinal fluid, bile, semen and amniotic fluid [16, 17]. The circadian rhythm of melatonin secretion is ...

Abstract Melatonin is the time-keeping molecule of vertebrates. The daily and annual variations of its rhythmic production allow synchronizing metabolism, physiological functions and behaviour to the environment changes. In fish, melatonin is produced by the photoreceptors of the pineal organ and retina as well as by other retinal cell types in the inner nuclear and ganglion cell layers. In most species, the melatonin rhythm displays a high-at-night profile, resulting from the circadian control of the arylalkylamine N-acetyltranferase (AANAT) activity. AANAT is the penultimate enzyme in the melatonin biosynthesis pathway. This review summarizes our current knowledge on the molecular and cellular mecha- nisms controlling the rhythmic production of melatonin, as well as on the targets and modes of action of the hormone in fish, with special emphasis on neuroendocrine functions.. ...

The brain is a powerhouse for activity. There are so many things happening at once in your brain and some of them we dont even realize are going on. The brain governs all of the responses for our bodies and produces these responses as well.

CONCLUSIONS: It appears likely that changes in pineal melatonin production cannot be correlated directly with the effects of pinealectomy on the crypts, although melatonin production was not measured in this case. The role of loss of the non-adrenergic innervation of the pineal in the effect of pinealectomy needs to be examined. There is also other experimental evidence that melatonin-free extracts of the pineal, containing as yet unidentified substances, can influence mitotic activity in some tissues, so the possible role of these substances in the effects of pinealectomy should also be considered. Furthermore, the superior cervical ganglion itself has an extra-pineal role. Changes in pineal sympathetic innervation are not significant in the hyperproliferative effects of pinealectomy on the intestinal crypts..... Read abstract Full text PDF ...

Aralkylamine N-acetyltransferase (AANAT) (EC 2.3.1.87), also known as arylalkylamine N-acetyltransferase or serotonin N-acetyltransferase (SNAT), is an enzyme that is involved in the day/night rhythmic production of melatonin, by modification of serotonin. It is in humans encoded by the ~2.5 kb AANAT gene containing four exons, located on chromosome 17q25. The gene is translated into a 23 kDa large enzyme. It is well conserved through evolution and the human form of the protein is 80% identical to sheep and rat AANAT. It is an acetyl-CoA-dependent enzyme of the GCN5-related family of N-acetyltransferases (GNATs). It may contribute to multifactorial genetic diseases such as altered behavior in sleep/wake cycle and research is on-going with the aim of developing drugs that regulate AANAT function. The systematic name of this enzyme class is acetyl-CoA:2-arylethylamine N-acetyltransferase. Other names in common use include: AANAT Arylalkylamine N-acetyltransferase Melatonin rhythm enzyme Serotonin ...

Mitochondrial fatty-acid beta-oxidation (mFAO) plays a central role in mammalian energy metabolism. Multiple severe diseases are associated with defects in this pathway. Its kinetic structure is characterized by a complex wiring of which the functional implications have hardly been explored. Repetitive cycles of reversible reactions, each cycle shortening the fatty acid by two carbon atoms, evoke competition between intermediates of different chain lengths for a common set of promiscuous enzymes (enzymes with activity towards multiple substrates). In our validated kinetic model of the pathway, substrate overload causes a steep and detrimental flux decline. Here, we unravel the underlying mechanism and the role of enzyme promiscuity in it. Comparison of alternative model versions elucidated the role of promiscuity of individual enzymes. Promiscuity of the last enzyme of the pathway, medium-chain ketoacyl-CoA thiolase (MCKAT), was both necessary and sufficient to elicit the flux decline. ...
