PGM18 in two German families
PGMl-isoenzymes with a mobil i ty slower than a seem to be very rare (Hopkinson and Harris, 1966; Giblett, 1969; Yunis, 1969). Fami ly studies were impossible till now. We observed two not related German families with the allele PGM~ (Fig. 1). The pedigrees are shown in Fig. 2. The compilation of all findings in these families (Table) gives no evidence for linkage. We found these two families within al together 2200 PGMl-investigations. Our observation confirms the suggestion, t ha t PGM~ is a rare allele of the phosphoglueomntase.
Seltene PGM-Phänotypen in einer Stichprobe aus dem süddeutschen Raum
SummaryIn a random test of 2874 persons of southern Germany the phenotypes 3-1 and 6-2 were found in the PGM system. The photographs illustrate that in cases of incomplete separation the determination of these phenotypes is incouclusive.ZusammenfassungIn einer Stichprobe von 2874 Personen aus dem süddeutschen Raum werden dreimal der Phänotyp 3-1, einmal der Phänotyp 6-2 gefunden.
Optical rotatory dispersion and absolute configuration—III
Abstract Optical rotatory dispersion measurements on pyrrolidine, piperidine, and tetrahydro-isoquinoline alkaloids indicate that the absolute configuration of the α-asymmetric center may be assigned directly from the dispersion curve, provided either that the nitrogen atom is not protonated, or that the compound contains a chromophore absorbing above 200 mμ.
