Diversity of FAAL enzymes and prediction of their substrate specificity using FAALPred

Protein Science, Volume 35, Issue 2, February 2026.
Abstract FAALs (fatty acyl‐AMP ligases) recruit and incorporate fatty acids during the biosynthesis of secondary metabolites. Their diversity, distribution, and substrate specificity remain poorly understood, which limits functional predictions from sequence data.

Ultrastructure of Naegleria fowleri enflagellation [PDF]

Journal of Bacteriology, 1981
Amoebae of Naegleria fowleri nN68 became elongated flagellated cells 150 to 180 min after subculture to non-nutrient buffer. N. fowleri NF69 did not become elongated or flagellated under these conditions. Electron microscopic examination of N. fowleri confirmed that it is a typical eucaryotic protist with a distinct nuclear envelope and prominent ...

Isolation and Identification of Naegleria Species from Environmental Water in Changchun, Northeastern China

Iranian Journal of Parasitology, 2014
Background: Naegleria is a free-living amoeba, and pathogenic Naegleria may pose a health risk to people exposed to recreational water. Our objective in this study was to determine if there are pathogenic amoebae in environmental water samples from ...

The genome of Naegleria lovaniensis, the basis for a comparative approach to unravel pathogenicity factors of the human pathogenic amoeba N. fowleri

BMC Genomics, 2018
Background Members of the genus Naegleria are free-living eukaryotes with the capability to transform from the amoeboid form into resting cysts or moving flagellates in response to environmental conditions.

Identification of Potential Therapeutic Agents for Primary Amebic Meningoencephalitis Using Text Mining and Bioinformatics Analyses

Analytical Cellular Pathology, Volume 2026, Issue 1, 2026.
Naegleria fowleri, the brain‐eating ameba, causes primary amebic meningoencephalitis (PAM), a fatal infectious disease that affects the central nervous system (CNS). We aimed to evaluate the functions and potential drugs targeting PAM using text mining and bioinformatics analyses.

GalNAc Carbohydrate Prevents the Formation of Neutrophil Extracellular Traps and Increase Myeloperoxidase Enzyme Activity in Interactions of Neutrophils and Entamoeba histolytica Preincubated With GalNAc

BioMed Research International, Volume 2026, Issue 1, 2026.
During amoebic infection, neutrophils are the first cells of the immune system to interact with trophozoites of Entamoeba histolytica, initiating amoebicidal activity. Different lectins and carbohydrates can participate in the mechanism of adhesion between E.

Identification and molecular typing of Naegleria fowleri from a patient with primary amebic meningoencephalitis in China

International Journal of Infectious Diseases, 2018
Naegleria fowleri is the only Naegleria spp. known to cause an acute, fulminant, and rapidly fatal central nervous system infection in humans called primary amebic meningoencephalitis (PAM).
