Sea urchin DNA methyltransferases
Cell Biophysics, 1989DNA methyltransferase activities have been partially purified from unfertilized eggs and blastula nuclei of sea urchin embryos. Comparative studies, using different DNAs as substrates, show that the two preparations are most active on hemimethylated and single-strand DNA, but they methylate, though at a lower rate, also on double-strand DNA.

Summaryi. The head of the sea‐urchin spermatozoon is pear‐shaped and axially symmetrical. The sub‐microscopic morphology of the middle piece has not been investigated, but the tail, which terminates in an axial fibre, probably contains spiral or coiled structures, as in mammalian spermatozoa.2.

Publisher Summary The chapter describes the structures and functions of sea urchin spermatozoa. Methods for the isolation of different parts of the sea urchin sperm are discussed. Sea urchin sperm are specialized for five functions: (1) oxidative phosphorylation to produce ATP, (2) flagellar motility, (3) the acrosome reaction, (4) binding to the egg,

Injuries from sea urchins result from penetration of the calcareous spines into the skin. Local pain of several days' duration is the most common symptom, but systemic reaction from toxins found in certain species can occur. There is no uniformly accepted successful treatment other than cleansing the wound.
