Researcher found that iPFK2 has a beta-hairpin N-terminal structure that secures the binding of fructose-6-phosphate to the active site via interaction with the protein's ‘2-Pase’ domain. There are two active pockets within iPFK2 for fructose-2,6-bisphosphatase and 6-phosphofructo-2-kinase which are structurally different.
PHP-GTK is a set of language bindings for the programming language PHP which allow GTK graphical user interface (GUI) applications to be written in PHP. PHP-GTK provides an object-oriented programming interface to GTK classes and functions. PHP-GTK partly supports GTK2, but GTK3 is unsupported. [1]
Immediately invoked function expressions may be written in a number of different ways. [3] A common convention is to enclose the function expression – and optionally its invocation operator – with the grouping operator, [4] in parentheses, to tell the parser explicitly to expect an expression.

[35] User-defined functions can be created at any time and without being prototyped. [35]
As an example, PHP has a direct module interface called SAPI for different web servers; [2] in the case of PHP 5 and Apache 2.0 on Windows, it is provided in the form of a DLL file called php5apache2.dll, [3] which is a module that, among other functions, provides an interface between PHP and the web server, implemented in a form that the ...
The PHP Standard Recommendation (PSR) is a PHP specification published by the PHP Framework Interop Group. Similar to Java Specification Request for Java, it serves the standardization of programming concepts in PHP. The aim is to enable interoperability of components and to provide a common technical basis for implementation of proven concepts ...
In computer programming, an anonymous function (function literal, expression or block) is a function definition that is not bound to an identifier. Anonymous functions are often arguments being passed to higher-order functions or used for constructing the result of a higher-order function that needs to return a function. [ 1 ]
