Wells*†, and Roger L. Miesfeld*† Departments of §Chemistry and *Biochemistry and Molecular Biophysics and †Center for Insect Science, University of Arizona, Tucson, AZ 85721-0088 Edited by Anthony A. James, University of California, Irvine, CA, and approved December 4, 2007 (received for review August 27, 2007) We demonstrate the presence of an alternate metabolic pathway We previously reported that mosquitoes dispose of toxic for urea synthesis in Aedes aegypti mosquitoes that converts uric ammonia through glutamine (Gln) and proline (Pro) synthesis, acid to urea via an amphibian-like uricolytic pathway. For these along with excretion of ammonia, uric acid, and urea (20). By studies, female mosquitoes were fed a sucrose solution containing using labeled isotopes and mass spectrometry techniques (21), 15 15 15 15 15 NH4Cl, [5- N]-glutamine, [ N]-proline, allantoin, or allantoic we have recently determined how the N from NH4Cl is acid. At 24 h after feeding, the feces were collected and analyzed incorporated into the amide side chain of Gln, and then into Pro, in a mass spectrometer. Specific enzyme inhibitors confirmed that in Ae. aegypti (22). In the present article we demonstrate that the 15 15 15 mosquitoes incorporate N from NH4Cl into [5- N]-glutamine nitrogen of the amide group of Gln contributes to uric acid and use the 15N of the amide group of glutamine to produce synthesis in mosquitoes and, surprisingly, that uric acid can be 15 labeled uric acid. -
ASPA Gene Aspartoacylase
ASPA gene aspartoacylase Normal Function The ASPA gene provides instructions for making an enzyme called aspartoacylase. In the brain, this enzyme breaks down a compound called N-acetyl-L-aspartic acid (NAA) into aspartic acid (an amino acid that is a building block of many proteins) and another molecule called acetic acid. The production and breakdown of NAA appears to be critical for maintaining the brain's white matter, which consists of nerve fibers surrounded by a myelin sheath. The myelin sheath is the covering that protects nerve fibers and promotes the efficient transmission of nerve impulses. The precise function of NAA is unclear. Researchers had suspected that it played a role in the production of the myelin sheath, but recent studies suggest that NAA does not have this function. The enzyme may instead be involved in the transport of water molecules out of nerve cells (neurons). Health Conditions Related to Genetic Changes Canavan disease More than 80 mutations in the ASPA gene are known to cause Canavan disease, which is a rare inherited disorder that affects brain development. Researchers have described two major forms of this condition: neonatal/infantile Canavan disease, which is the most common and most severe form, and mild/juvenile Canavan disease. The ASPA gene mutations that cause the neonatal/infantile form severely impair the activity of aspartoacylase, preventing the breakdown of NAA and allowing this substance to build up to high levels in the brain. The mutations that cause the mild/juvenile form have milder effects on the enzyme's activity, leading to less accumulation of NAA. -

Supplemental Methods
Supplemental Methods: Sample Collection Duplicate surface samples were collected from the Amazon River plume aboard the R/V Knorr in June 2010 (4 52.71’N, 51 21.59’W) during a period of high river discharge. The collection site (Station 10, 4° 52.71’N, 51° 21.59’W; S = 21.0; T = 29.6°C), located ~ 500 Km to the north of the Amazon River mouth, was characterized by the presence of coastal diatoms in the top 8 m of the water column. Sampling was conducted between 0700 and 0900 local time by gently impeller pumping (modified Rule 1800 submersible sump pump) surface water through 10 m of tygon tubing (3 cm) to the ship's deck where it then flowed through a 156 µm mesh into 20 L carboys. In the lab, cells were partitioned into two size fractions by sequential filtration (using a Masterflex peristaltic pump) of the pre-filtered seawater through a 2.0 µm pore-size, 142 mm diameter polycarbonate (PCTE) membrane filter (Sterlitech Corporation, Kent, CWA) and a 0.22 µm pore-size, 142 mm diameter Supor membrane filter (Pall, Port Washington, NY). Metagenomic and non-selective metatranscriptomic analyses were conducted on both pore-size filters; poly(A)-selected (eukaryote-dominated) metatranscriptomic analyses were conducted only on the larger pore-size filter (2.0 µm pore-size). All filters were immediately submerged in RNAlater (Applied Biosystems, Austin, TX) in sterile 50 mL conical tubes, incubated at room temperature overnight and then stored at -80oC until extraction. Filtration and stabilization of each sample was completed within 30 min of water collection. -
