About Textpresso Categories/Ontology Copyright Downloads Feedback Home Query Language Search User Guide
Enter keyword(s) and/or category/ies. Selecting categories for a query makes a search more specific. For example, you can retrieve sentences that contain the word HSN and a Oryza sativa gene name by typing the keyword 'SPW1' and choosing the category 'gene (Oryza sativa)'. A category hit occurs when a particular word or phrase in the sentence is defined as a member of a particular category. Categories will be concatenated by a Boolean 'and' operation to other categories and keyword(s) if present. To search for terms in categories, click on the Categories/Ontology link above.
Keywords
Separate multiple, required keywords by white spaces (Boolean 'and').
Separate multiple, alternative keywords by a comma with no white spaces (Boolean 'or').
Enter phrases in double quotes, and put a '-' sign in front of words which are to be excluded.

Narrow your search results with filter:
Put a '+' sign in front of words which have to be included, a '-' sign in front of words which have to be excluded. Enter the field of the word, viz author, title, year, journal, abstract, type or sentence in square brackets. Enter phrases in double quotes.
For example, to find all the papers in the search result that have Jack as author, but not John, enter +Jack-John[author]. To exclude all papers that have the phrase double mutant in title, enter -"double mutant"[title]. You can combine several filters and enter something like +Jack-John[author] -"double mutant"[title] +1994[year] -review[type].

Title: Functional roles of protein domains on rice alpha-amylase activity .
Author: Terashima M Hosono M Katoh S
Journal: Appl . Microbiol . Biotechnol . Citation: V : 47 ( 4 ) P : 364-7 Year: 1997 Type: ARTICLE
Literature: oryza Field: abstract Doc ID: pub9163949 Accession (PMID): 9163949
Matching Sentences:
[ Sen. 2, subscore: 2.00 ]: The enzymes that have an Amy1A-type N-terminal domain , Amy1A and Amy1A/3D , showed high activity against soluble starch , while the enzymes that have an Amy3D-type barrel structure , Amy3D and Amy1A/3D , showed high activity in oligosaccharide hydrolysis .
[ Sen. 1, subscore: 1.00 ]: Characteristics of two rice alpha-amylases Amy1A and Amy3D , and those of two chimeric enzymes Amy1A/3D and Amy3D/1A , engineered from the two isozymes , were compared in the light of the functional roles of protein domains in alpha-amylase .
[ Sen. 5, subscore: 1.00 ]: We have already characterized two rice alpha-amylase isozymes , Amy1A and Amy3D , and a chimeric enzyme engineered from these two isozymes , Amy1A/3D ( Terashima et al 1995 , 1996a , b ) .
[ Sen. 6, subscore: 1.00 ]: In spite of the high homology ( 70% ) of their amino acid sequences , Amy1A and Amy3D showed distinct differences in their enzymatic characteristics .
[ Sen. 7, subscore: 1.00 ]: The chimeric enzyme Amy1A/3D , which consists of an Amy1A-type N-terminal domain and an Amy3D-type barrel structure , inherited enzymatic characteristics from the both isozymes .

Title: Characterization of rice alpha-amylase isozymes expressed by Saccharomyces cerevisiae .
Author: Terashima M Katoh S Thomas BR Rodriguez RL .
Journal: Appl . Microbiol . Biotechnol . Citation: V : 43 ( 6 ) P : 1050-5 Year: 1995 Type: ARTICLE
Literature: oryza Field: abstract Doc ID: pub8590656 Accession (PMID): 8590656
Matching Sentences:
[ Sen. 4, subscore: 1.00 ]: The pH optima for Amy3D ( pH optimum 5 . 5 ) and Amy1A ( pH optimum 4 . 2 ) correlate with the pH of the endosperm it issue at the times in rice seedling development when these isozymes are produced .
[ Sen. 5, subscore: 1.00 ]: Amy3D showed 10-14 times higher reactivity to oligosaccharides than Amy1A .
[ Sen. 6, subscore: 1.00 ]: Amy1A , on the other hand , showed higher reactivity to soluble starch and starch granules than Amy3D .
[ Sen. 7, subscore: 1.00 ]: These results suggest that the isozyme Amy3D , which is expressed at an early stage of germination , produces sugars from soluble starch during the early stage of seed germination and that the isozyme Amy1A works to initiate hydrolysis of the starch granules .

Matching Sentences:
[ Sen. 1, subscore: 1.00 ]: The thermostability and kinetics of starch hydrolysis were compared between a rice alpha-amylase isozyme Amy1A and its mutant enzyme that lacks an N-linked carbohydrate chain .
