The dinucleotide binding beta alpha beta motif in the crystal structures of seven different enzymes has been analysed in terms of their three-dimensional structures and primary sequences. We have identified that the hydrogen bonding of the adenine ribose to the glycine-rich turn containing the fingerprint sequence GXGXXG/A occurs via a direct or indirect(More)
Streptomyces albus ATCC 3005 was found to produce higher levels of extracellular peroxidase activity (3.420 U mg(-1)) than previously reported for any other actinomycete. Maximum peroxidase activity was obtained after 72 h of incubation at a temperature of 30 degrees C in a liquid medium (pH 7.6) containing (in w/v) 0.8% to 0.9% oat spelts xylan and 0.6%(More)

The influence of social and economic institutions on fertility and contraception were examined by collecting data from the guardians of these institutions, 1.e., community leaders. Recently, the International Center for Diarrheal Disease Research, Bangladesh (ICDDR,B) conducted an operation research project in 4 rural upazila -- Sirajganj, Gopalpur,(More)
Various dialysis methods are commonly employed for the crystallization of proteins. Typical procedures include the use of dialysis bags, dialysis buttons or Zeppezauer microdiffusion cells. The general principle involved is that the protein solution is gradually brought to a point of supersaturation by imposing a gradient of ionic strength or organic(More)
A nationally representative sample of 8 percent of the Government of Pakistan's primary family planning service facilities, the Family Welfare Centres (FWC), was carried out at the request of the Ministry of Population Welfare in mid-1992. The "situation analysis" approach used involved: 1) observation and inventory of services, facilities, supplies and(More)
Polyacrylamide gel electrophoresis (PAGE) is a common technique used in Biochemistry for separation of macromolecules [I]. It is particularly useful to ascertain the degree of protein purity and confirm molecular masses obtained from chromatographic methods [2-51. In addition PAGE can be developed as zymogram (native gel) to detect the presence of enzyme(More)
In spite of three decades of national family planning programmes, Pakistan's contraceptive prevalence rate was only 12 percent in 1991. Furthermore, the government family planning service delivery systems, primarily the family welfare center (FWC), cover less than 10 percent of the people in rural areas. Although there are cultural and religious constraints(More)
