'''STRUCTURE OF GREEN ABALONE LYSIN DIMER'''<br />


==Overview==
==STRUCTURE OF GREEN ABALONE LYSIN DIMER==
Abalone sperm lysin is a 16 kDa acrosomal protein used by sperm to create, a hole in the egg vitelline envelope. Lysins from seven California abalone, exhibit species-specificity in binding to their egg receptor, and range in, sequence identity from 63 % to 90 %. The crystal structure of the sperm, lysin dimer from Haliotis fulgens (green abalone) has been determined to, 1.71 A by multiple isomorphous replacement. Comparisons with the structure, of the lysin dimer from Haliotis rufescens (red abalone) reveal a similar, overall fold and conservation of features contributing to lysin's, amphipathic character. The two structures do, however, exhibit differences, in surface residues and electrostatics. A large clustering of, non-conserved surface residues around the waist and clefts of the dimer, and differences in charged residues around these regions, indicate areas, of the molecule which may be involved in species-specific egg recognition.

== Function ==
[https://www.uniprot.org/uniprot/ELYS_HALFU ELYS_HALFU] Dissolves the egg vitelline layer nonenzymatically during fertilization. It creates a hole of about 3 mu-m in diameter through which the sperm pass.
