Na,K-ATPase activity and epithelial interfaces in gills of the freshwater shrimp Macrobrachium amazonicum (Decapoda, Palaemonidae)
Belli N, Faleiros R, Firmino K, Masui D, Leone F, McNamara J, et al.
Comp Biochem Physiol A Mol Integr Physiol . 2008 Dec; 152(3):431-9. PMID: 19100333
Diadromous freshwater shrimps are exposed to brackish water both as an obligatory part of their larval life cycle and during adult reproductive migration; their well-developed osmoregulatory ability is crucial to...

The crustacean gill (Na+,K+)-ATPase: allosteric modulation of high- and low-affinity ATP-binding sites by sodium and potassium
Masui D, Silva E, Mantelatto F, McNamara J, Barrabin H, Scofano H, et al.
Arch Biochem Biophys . 2008 Sep; 479(2):139-44. PMID: 18796291
The blue crab, Callinectes danae, tolerates exposure to a wide salinity range employing mechanisms of compensatory ion uptake when in dilute media. Although the gill (Na+,K+)-ATPase is vital to hyperosmoregulatory...

Gill (Na+,K+)-ATPase in diadromous, freshwater palaemonid shrimps: species-specific kinetic characteristics and alpha-subunit expression
Santos L, Belli N, Augusto A, Masui D, Leone F, McNamara J, et al.
Comp Biochem Physiol A Mol Integr Physiol . 2007 May; 148(1):178-88. PMID: 17521934
To better comprehend physiological adaptation to dilute media and the molecular mechanisms underlying ammonia excretion in palaemonid shrimps, we characterized the (Na+,K+)-ATPase from Macrobrachium amazonicum gills, disclosing high- (K(0.5) =...

K+ and NH4(+) modulate gill (Na+, K+)-ATPase activity in the blue crab, Callinectes ornatus: fine tuning of ammonia excretion
Garcon D, Masui D, Mantelatto F, McNamara J, Furriel R, Leone F
Comp Biochem Physiol A Mol Integr Physiol . 2007 Feb; 147(1):145-55. PMID: 17276114
To better comprehend the mechanisms of ionic regulation, we investigate the modulation by Na+, K+, NH4(+) and ATP of the (Na+, K+)-ATPase in a microsomal fraction from Callinectes ornatus gills....

Structural and kinetic alterations of constitutive conidial alkaline phosphatase from the osmotically-sensitive mutant of Neurospora crassa
Bogo K, Masui D, Leone F, Jorge J, Furriel R
Folia Microbiol (Praha) . 2006 Dec; 51(5):431-7. PMID: 17176763
The osmotically-sensitive os-1 mutant of Neurospora crassa overproduced conidial alkaline phosphatase. The enzyme was purified by Phenyl-Sepharose CL-4B chromatography and Sephadex G-200 gel filtration. PAGE analysis of the purified enzyme...
