In vitro and in vivo characterization of the multiple isoforms of Schistosoma mansoni hypoxanthine-guanine phosphoribosyltransferases

Abstract: SmHGPRT-Schistosoma mansoni hypoxanthine-guanine phosphoribosyltransferase PRPP-5-phosphorylribose 1-pyrophosphate IMP-inosine monophosphate GMP-guanosine monophosphate Database The atomic coordinates and structure factors for the Schistosoma mansoni hypoxanthineguanine phosphoribosyltransferase can be found in the RCSB Protein Data Bank (http://www.rcsb.org) under the accession code 5IPF.

“…Análises comparativas entre a sequência peptídica de SmHGPRT-1 e todas as outras HGPRTs depositadas no PDB indicaram que dez resíduos (Leu74, Gly76, Leu84, Glu140, Asp141, Thr148, Lys172, Gly196, Asp200 e Arg206) estão conservados entre eles, estando cinco deles localizados no sítio ativo 1 da proteína, como mostrado na figura 1 (ROMANELLO et al, 2019).…”

“…De acordo comRomanello (2019), os aminoácidos Asp144, Gly146 e Val194 são fundamentais no mecanismo de reação enzimática com substratos naturais da HGPRT. Os aminoácidos presentes no sítio de ligação 1 são: Lys172, Gly146, Lys147, Asp144, Asp200, Val194, Phe193, Thr145, Ile142, Glu 140, Asp141 e Thr148.…”

“…SmHGPRTases also show high expression in female adult worms. Previous studies suggest that these genes may be involved in the parasite’s sexual maturation ( Romanello et al, 2019 ). Also, whole-mount in situ hybridization experiments show that SmHGPRTase 2 is present along the body of male and female worms, possibly indicating a sexual specialization role for this enzyme ( Romanello et al, 2019 ).…”

Also, whole-mount in situ hybridization experiments show that SmHGPRTase 2 is present along the body of male and female worms, possibly indicating a sexual specialization role for this enzyme ( Romanello et al, 2019 ). Genes that code for SmHGPRTases were also found up-regulated in parasites 28 days after infection in the mammalian host, suggesting a possible role for these enzymes in the synthesis of molecules necessary for egg production ( Buddenborg et al, 2019 ).…”
