Alpha globin gene number: population and restriction endonuclease studies.
Restriction endonuclease analysis was used to test a proposed genetic model using alpha-globin gene number to account for the observed distributions of the proportions of hemoglobin (Hb) S in sickle cell trait. In a subsample of specimens collected during a population survey in India, these studies confirmed that the postulated genotype was present in 22 of the 23 individuals examined. In the s...
متن کاملChimeric restriction endonuclease.
Fok I restriction endonuclease recognizes the nonpalindromic pentadeoxyribonucleotide 5'-GGATG-3'.5'-CATCC-3' in duplex DNA and cleaves 9 and 13 nt away from the recognition site. Recently, we reported the presence of two distinct and separable domains within this enzyme: one for the sequence-specific recognition of DNA (the DNA-binding domain) and the other for the endonuclease activity (the c...
متن کاملBiologically inactive growth hormone caused by an amino acid substitution.
Short stature caused by biologically inactive growth hormone (GH) is characterized by lack of GH action despite high immunoassayable GH levels in serum and marked catch-up growth to exogenous GH administration. We found a heterozygous single-base substitution (A-->G) in exon 4 of the GH-1 gene of a girl with short stature, clinically suspected to indicate the presence of bioinactive GH and resu...
متن کاملRestriction glycosylases: involvement of endonuclease activities in the restriction process
All restriction enzymes examined are phosphodiesterases generating 3'-OH and 5'-P ends, but one restriction enzyme (restriction glycosylase) excises unmethylated bases from its recognition sequence. Whether its restriction activity involves endonucleolytic cleavage remains unclear. One report on this enzyme, R.PabI from a hyperthermophile, ascribed the breakage to high temperature while another...
متن کاملStudies with human growth hormone.
Let me tell you at the outset of my appreciation of the great honour you have done me in asking me to deliver the first Lawson Wilkins Memorial Lecture. I accepted this invitation with eagerness because I cherish any link that binds Lawson Wilkins' life and work to mine. I often turn to the page in the second edition of his great textbook in which he proudly listed the 31 Associates and Fellows...
