13. Structure and expression of STK, a src-related gene in the simple metazoan Hydra attenuata.
Both cDNA clones and a genomic DNA clone encoding a 509-amino-acid protein that is 64% similar to chicken pp60c-src were isolated from the simple metazoan Hydra attenuata. We have designated this gene STK, for src-type kinase. Features of the amino acid sequence of the protein encoded by the STK gene suggest that it is likely to be myristoylated and regulate

14. Isolation and amino acid sequence of a morphogenetic peptide from hydra
From Anthopleura elegantissima and from Hydra attenuata, a morphogenetic peptide—the head activator—was isolated in pure form. The sequence of the head activator was established by enzymatic and by chemical degradation of the whole peptide or fragments thereof and subsequent analysis of the amino acids by micromethods. The head activator from both source

15. Conservation of the prohormone convertase gene family in metazoa: analysis of cDNAs encoding a PC3-like protein from hydra.
A subclass of proteolytic enzymes that correctly cleave precursor proteins at paired basic residues and are structurally related to the bacterial subtilisins has recently been identified. In yeast, a single membrane-bound proteolytic processing enzyme encoded by the kex2 gene has been found, whereas in higher vertebrates cDNAs encoding four distinct enzymes
