Switching the substrate specificity of lysoplasmalogen‐specific phospholipase D

FEBS Open Bio, Volume 11, Issue 4, Page 1132-1143, April 2021., 2021
Lysoplasmalogen‐specific phospholipase D (LyPls‐PLD) intrinsically has a high affinity for choline lysoplasmalogen (LyPlsCho). By rational site‐directed mutagenesis (F211L), we converted LysPls‐PLD to a version (LysoPAF‐PLD) that has a high affinity for LysoPAF rather than the natural substrate LyPlsCho.

Refugia Preferences by the SpidersLoxosceles reclusaandLoxosceles laeta(Araneae: Sicariidae) [PDF]

Journal of Medical Entomology, 2008
A variety of refugia were offered to different instars of brown recluse spiders, Loxosceles reclusa Gertsch and Mulaik, and a South American recluse spider, L. laeta (Nicolet), to determine whether they preferred certain types of refugia spaces. Variables included (1) crevice widths ranging from 3.2 to 21 mm, (2) horizontal and vertical orientations ...

Heterophilic antibodies in sera from individuals without loxoscelism cross-react with phospholipase D from the venom of Loxosceles and Sicarius spiders

Journal of Venomous Animals and Toxins including Tropical Diseases, 2018
Background Loxoscelism is a severe human envenomation caused by Loxosceles spider venom. To the best of our knowledge, no study has evaluated the presence of antibodies against Loxosceles venom in loxoscelism patients without treatment with antivenom ...
