N-terminal amino-sequencing of camel (Camelus dromedarius) luteinizing-hormone alpha and beta-subunits.
The subunits of luteinizing hormone from the Camelus dromedarius (CamLH) have been separated by reverse phase HPLC after reduction and alkylation of their disulfide bridges. The N-terminal amino-acid sequencing of the alpha and beta subunits has been performed up to the 53rd and 67th residue respectively (i.e. more than half of each polypeptide chain). These sequences have been compared to those of LH from other mammalian species in order to estimate the phylogenetic divergence of LH in this species and in order to point out characteristic features of its primary structure that can be related to its physico-chemical properties.
