Abstract

A sulphated glycoprotein, denoted I-SG, has previously been shown to be synthesized in Volvox under developmental control [(1982) FEBS Lett. 143, 311-315]. It is demonstrated that I-SG synthesis is restricted to a period during embryonic inversion as short as 10 min (out of the 48 h life cycle). This glycoprotein was purified and chemically characterized. 62% of its amino acid residues are ...
