Crystal structure of saposin B reveals a dimeric shell for lipid binding
(National Academy of Sciences, 2003)
Saposin B is a small, nonenzymatic glycosphingolipid activator
protein required for the breakdown of cerebroside sulfates (sulfatides) within the lysosome. The protein can extract target lipids
from membranes, forming ...
Identification of a novel protein with guanylyl cyclase activity in Arabidopsis thaliana
(Elsevier, 2003)
Guanylyl cyclases (GCs) catalyze the formation of the
second messenger guanosine 3 ,5 -cyclic monophos-
phate (cGMP) from guanosine 5 -triphosphate (GTP).
While many cGMP-mediated processes in plants have
been reported, ...
