The major locus for multifactorial nonsyndromic cleft lip maps to mouse Chromosome 11

Cleft lip with or without cleft palate, CL(P), a common human birth defect, has a genetically complex etiology. An animal model with a similarly complex genetic basis is established in the A/WySn mouse strain, in which 20% of newborn have CL(P). Using a newly created congenic strain, AEJ.A, and SSLP markers, we have mapped a major CL(P)-causing gene derived from the A/WySn strain. This locus, here named clf1 (cleft lip) maps to Chromosome (Chr) 11 to a region having linkage homology with human 17q21-24, supporting reports of association of human CL(P) with the retinoic acid receptor alpha (RARA) locus.     

Purification and properties of the endocellular β-glucosidase of Candida cacaoi Buckley and Van Uden CBS 2020

D. DRIDER, P. POMMARES, P. CHEMARDIN, A. ARNAUD AND P. GALZY. 1993. The endocellular enzyme β-glucosidase of Candida cacaoi was purified by ion-exchange chromatography and gel filtration. The molecular weight was 220 ± 10 kDa; its optimum pH was between 4 and 5.5 and its optimum temperature was 60C. This enzyme was active against soluble glucosides tested with β(1–2), β(1–3), β(1–4) and even α(1–4) and α(1–6) and was inhibited by D-glucono-δ-lactone. The enzyme was constitutive but its synthesis was repressed by glucose.
