A 4.2-kb PstI fragment harboring the gene cluster of the ribulose monophosphate (RuMP) pathway for formaldehyde fixation was identified in the chromosome of a gram-positive, facultative methylotroph, Mycobacterium gastri MB19, by using the coding region of 3-hexulose-6-phosphate synthase (HPS) as the hybridization probe. The PstI fragment contained three complete open reading frames (ORFs) whic...
BACKGROUND & OBJECTIVES The search for effective polymorphic markers in Plasmodium vivax is highly demanding to understand its transmission in a population. Due to the limited knowledge existing for P. vivax, the search for polymorphic markers for population studies is ongoing. The MSP gene family of Plasmodia has been linked with immune evasion. To study the circulating parasite population P. ...
Genetic haemochromatosis (HFE) is a frequent and potentially fatal disease. Early phlebotomies may prevent complications. The recessive gene for HFE is unknown but closely linked to the HLA-A locus. No direct test for homozygosity for HFE is currently available, apart from HLA typing within the family of a patient with confirmed HFE. During a reverse genetic approach to identify the gene, we fo...
background: pulmonary tuberculosis (ptb) has recently become a major problem in developed countries especially in immune compromised hiv infected individuals. cytokines, their genes and receptors have been implicated in the protective immunity, pathophysiology and development of tuberculosis. material & methods: in the present study the genotype frequencies of a number of polymorphic genes co...
چکیده: آلفا تالاسمی یکی از شایع ترین بیماری های وراثتی هموگلوبین است که دارای الگوی توارثی اتوزومی مغلوب می باشد. بر خلاف بتا تالاسمی، شایع ترین علت بیماری حذف های ژنی بوده که منجر به حذف ژن های 1? و 2? در خوشه ژنی آلفا گلوبین می شود. خوشه ژنی آلفا گلوبین و دو ژن 1? و 2? گلوبین با شباهتی بیشتر از 96 درصد، بر روی کروموزوم 16 و موقعیت p13.3 قرار گرفته است. آنالیز پیوستگی و تعیین هاپلوتیپ های گو...
The streptomycete plasmid SCP2 and its mutant SCP2* (3, 4, 15) are 31-kilobase (kb) (10) sex factors (3) with one to five copies per cell (16). The SCP2 sequence can be stably cloned in Escherichia coli (12). SCP2* is suitable as a cloning vector in streptomycetes (2). Further developments of SCP2* into useful cloning vectors are described in this report. (Portions of this work were presented a...
