The complete amino-acid sequence of histone H2B(3) from sperm of the sea urchin Parechinus angulosus.

The primary structure of a third H2B histone isolated from sperm of the sea urchin Parechinus angulosus has been determined. H2B(3) consists of a polypeptide chain of the following 148 amino acid residues: Pro-Arg-Ser-Pro-Ala-Lys-Thr-Ser-Pro-Arg-Lys-Gly-Ser-Pro-Arg-Lys-Gly-Ser-Pro-Arg-Lys-Gly-Ser-Pro-Ser-Arg-Lys-Ala-Ser-Pro-Lys-Arg-Gly-Gly-Lys-Gly-Ala-Lys-Arg-Ala-Gly-Lys-Gly-Gly-Arg-Arg-Arg-Arg-Val-Val-Lys-Arg-Arg-Arg-Arg-Arg-Arg-Glu-Ser-Tyr-Gly-Ile-Tyr-Ile-Tyr-Lys-Val-Leu-Lys-Gln-Val-His-Pro-Asp-Thr-Gly-Ile-Ser-Ser-Arg-Ala-Met-Ser-Val-Met-Asn-Ser-Phe-Val-Asn-Asp-Val-Phe-Glu-Arg-Ile-Ala-Ser-Glu-Ala-Ser-Arg-Leu-Thr-Ser-Ala-Asn-Arg-Arg-Ser-Thr-Val-Ser-Ser-Arg-Glu-Ile-gln-Thr-Ala-Val-Arg-Leu-Leu-Leu-Pro-Gly-Glu-Leu-Ala-Lys-His-Ala-Val-Ser-Glu-Gly-Thr-Lys-Ala-Val-Thr-Lys-Tyr-Thr-Thr-Ser-Arg. H2B(3) Parechinus closely resembles HIB(2) Parechinus but has one additional repeating pentapeptide in the amino-terminal region and a serine replacing glycine at position 98.

Histone H2B variants from the erythrocytes of an amphibian, a reptile and a bird.

Histones H2B have been isolated from the terminally differentiated diploid erythrocytes of three different classes, amphibia (Xenopus laevis), reptilia (Crocodilus niloticus) and aves (Gallus domesticus). Partial amino acid sequences revealed three regions of sequence variation, each variant involving a single amino acid substitution.

Abnormal behaviour of proline in the isothiocyanate degradation.

It has been observed that proline residues often initiate overlaps during sequenator analysis. The cause has been shown to be an abnormally slow cleavage reaction. The kinetics of the cleavage reaction has been studied and found to obey pseudo-first-order kinetics. There are considerable differences in reaction rates depending on the position of proline in the sequence, as demonstrated for the four prolines in the N-terminal section of the H2B histone from chicken.
