Two phosphofructokinase genes have been described previously in Entamoeba histolytica. The product of the larger of the two genes codes for a 60-kDa protein that has been described previously as a pyrophosphate (PP(i))-dependent enzyme, and the produ

Pyrophosphate-dependent phosphofructokinase (PPi-PFK) gene from Entamoeba histolytica was cloned from its genomic library and sequenced. The open reading frame has 1149 by and codes for a protein of 41.5 kDa. The deduced amino acid sequence of E. his

SYNOPSIS. Numerous reports may be found in the literature on cytoplasmic and non-DNA utilization of tritium from H3-thymidine. Such reports underscore the need to clarify the metabolic fate of H3-thymidine. This investigation outlines the fate of thy

SYNOPSIS. Entamoeba histolytica grown with H3-thymidine in CLG medium took up tritium into DNase-sensitive material in the nucleus and cytoplasm. The distribution of nuclear activity indicated that the entire nucleus, including the peripheral chromat

SYNOPSIS. Autoradiographic studies were done which tested the effect of a potent DNA inhibitor, mitomycin C (MC) on the utilization of tritium from exogenous thymidine-methyl-H3 (TMH3) in Entamoeba histolytica grown with Bacteroides sp. in CLG medium

Ninhydrin-Schiff (NS) method revealed a higher level of protein-bound amino acids in diffuse and particulate form in cytoplasm of 72-hr, axenically grown amebae as compared to 72-hr cells from monoxenic cultures. Younger (24-hr) monoxenically grown a

Autoradiographs of sectioned Entamoeba histolytica labeled with [5-3H]uridine for time periods ranging from 15 sec to 24 hr revealed (1) some evenly distributed nuclear label and (2) extensive labeling of the peripheral nuclear chromatin. This nuclea

This review will concentrate on certain aspects of the nucleic acids of Entamoeba histolytica. Utilization and synthesis of purines and pyrimidines will initially be briefly discussed, e.g. salvage vs. de novo pathways, uptake studies and recognition

RNAs were isolated from Entamoeba histolytica with a high salt sodium dodecylsulfate-diethylpyrocarbonate technique. Majority species of 25 S, 17 S and 4 S RNAs were detected after sucrose gradient centrifugation. An additional 5 S RNA was detected b
